Section 1 Overview
1.1
Overview
The stub generator (hereafter referred to as RPCGEN) is a tool used to generate the source code of
the client and server stubs that are required whenever the remote procedure call (RPC) facility of
the HI7200/MP realtime operating system is to be used. A config file is created by using a text
editor and then input to RPCGEN, which creates the source code of the client and server stubs.

Section 3 Functions and Files Generated by RPCGEN
3.1.1
Client
(1) Client-initialization function
This function initiates the connection with the server. Specifying CLNT_NOINIT prevents the
creation of the client-initialization function.
(2) Client-shutdown function
This function ends the connection with the server. Specifying CLNT_NOSHUTDOWN prevents
the creation of the client-shutdown function.
(3) Client-stub functions
Each of these functions makes an RPC call and has the same API as or an API similar to the server
function. If SVRAUTH has not been specified, the API will be the same as that of the server
function. Specifying CLNTSTUB prevents the creation of a specific client-stub function.
3.1.2
Server
(1) Server-initialization function
This function starts up the server. Specifying SVR_NOINIT prevents the creation of the server-
initialization function.
(2) Server-shutdown function
This function shuts the server down. Specifying SVR_NOSHUTDOWN prevents the creation of
the server-shutdown function.
(3) Server-stub functions
Each of these functions is called back from the RPC library and then calls a server function.
Specifying SVRSTUB prevents the creation of a specific server-stub function, while specifying
SVRFUNC allows the name of the called server function to be replaced.

When the config file is “sample.x,” for example, RPCGEN will generate the following files:
sample_clnt.c, sample_clnt.h, sample_svr.c, sample_svr.h, sample_private.h, and sample_public.h.
To temporarily save information during the process of file generation, RPCGEN also generates
intermediate files in the current directory. The names of these intermediate files consist of two
underscores (“__”) appended before the filenames given in the table above.
(1) <config file>_clnt.c (client-stub source file)
This file contains the client-stub functions, client-initialization function, and client-shutdown
function.
(2) <config file>_clnt.h (client-stub header file)
This file contains definitions required for use of the client-stub functions, client-initialization
function, and client-shutdown function. The definitions include prototype declarations of the
client-stub functions, client-initialization function, and client-shutdown function.

Section 4 Executing RPCGEN
4.1
Executing RPCGEN
RPCGEN must be executed from the command prompt as follows.
perlΔ-I<rpcgen path>Δ<rpcgen path>\rpcgen.plΔ
<config file>[Δ<option>...](RET)
<rpcgen path> is a path to the directory where RPCGEN has been installed.
<config file> refers to a file describing the specifications of the client and server stubs to be
generated. This file must be created by the user. The standard filename extension for the config
file is “.x”, which must not be omitted when the name is entered in a command line.
After execution of the above command, RPCGEN will generate the C-language source files and
header files for the client and server stubs in accord with the information contained in the config
file.
If <config file> and <option> are omitted, the command syntax will be shown.

Section 5 Specifications of a Config File
Section 5 Specifications of a Config File
A config file contains definitions used for creation of the client and server stubs. Specifically, such
definitions are made by appending keywords for passing to RPCGEN to the API of the server
functions (as described in section 6, Definitions of Server Functions). Read this section carefully
before creating your own config file. The extension for config files is “.x.”
One config file corresponds to the definition of one server. Do not attempt to define multiple
servers within a single config file.
5.1
Definition
Definitions must be written in either of the following formats.
<keyword>{...};
<keyword>;
For certain definitions, two or more items can be entered between the braces {...}.
Example:
GLOBAL_INCFILE { “types.h” “rpc_public.h” };
A config file can include the following definitions.
(1) Locations where the files created by RPCGEN will be stored
•
•
•
•
•
PUB_INCPATH{…};
Path to <config file>_public.h
CLNT_SOURCEPATH{…}; Path to <config file>_clnt.c

Description:
This statement defines the server ID. The ID number can only be specified as a 4-byte integer
constant that can be represented as UINT32 or a C-language macro name to be replaced by such a
4-byte integer constant. If a C-language macro is used, this macro must have been defined in a file
specified by GLOBAL_INCFILE.
The server ID must, of course, be consistent across the entire system due to the specifications of
the HI7200/MP. RPCGEN does not detect duplication of server IDs.
The ID number is output to <config file>_public.h in the following format.
#define RPCSVR_ID_<server name> <ID number>
<Server name> refers to the server name defined with SVR_NAME.

SVR_NOSHUTDOWN
Format:
SVR_NOSHUTDOWN;
Description:
If this statement is present, RPCGEN will not create the server-shutdown function. Use
SVR_NOSHUTDOWN when the server-shutdown function is provided as part of the application.
The server-shutdown function generated by RPCGEN calls rpc_stop_server() to stop the server.
Although rpc_stop_server() generally allows specification of a callback function to be executed at
the time the server is stopped, no callback function is specifiable for the server-shutdown function
generated by RPCGEN. If you wish to use a callback function, specify SVR_NOSHUTDOWN
and implement the server-shutdown function on the user side.
Also refer to section 8.5, Server-Shutdown Function.

SVR_STATIC
Format:
SVR_STATIC{<size>Δ<section name>};
Description:
This statement defines the server as static. If this definition is omitted, the server will be dynamic.
Note that SVR_STATIC cannot be used in conjunction with SVR_NOINIT.
<Size> indicates the size of the server parameter area. Specify an integer constant that can be
represented as UINT32. The specified value is rounded up to the nearest multiple of four.
<Section name> indicates the section name to be given to the server parameter area. Note,
however, that the actual section name will be ‘B’ followed by the section name given here. This
<section name> is not affected by definition of SVR_SECTION.
The server-parameter area information is output to <config file>_svr.c in the following format.
#pragma section <section name>
#pragma pack 4
static UINT8 ucServerArea_<server name>[ ALIGNUP4(<size>) ];
#pragma unpack
#pragma section
Note:
Since the SH2A-DUAL does not have a facility for the CPU cores to snoop on each other’s
caches, the server parameter area must be allocated in a non-cacheable area. Specify a section
name that can be distinguished from those of sections to be allocated in cacheable areas.

SVR_AUTH
Format:
SVR_AUTH;
Description:
There are two ways to assign the server ID and server version.
(1) Model 1
Model 1 applies when SVR_AUTH has not been specified.
In this model, the application does not recognize the server ID or server version. The server ID
and server version are determined within the client and server stubs generated by RPCGEN.
Each of the client-stub functions has the same API as the original server function. Server IDs and
server version information passed to the following functions will be ignored.
•
•
•
•
Server-initialization function
Server-shutdown function
Client-initialization function
Client-shutdown function
RPCGEN outputs the definitions of the server ID and server version to <config file>_public.h.
Since the client-stub functions and server- and client- initialization and shutdown functions
generated by RPCGEN have include statements for <config file>_public.h, the server ID and
server version information is passed to the RPC library.
If RPCGEN-generated files for the client and server are from different generations, the RPC
library treats any RPC call as an error.

Section 5 Specifications of a Config File
(2) Model 2
Model 2 applies when SVR_AUTH has been specified.
In this model, the application assigns the server ID and server version. RPCGEN outputs
definitions of the server ID and server version in <config file>_public.h so that the application is
able to acquire this information.
Each of the client-stub functions is in the form of rpcclnt_<server name>_<server function name>
and its first and second parameters are the server ID and server version, respectively. The third and
subsequent parameters are the parameters of the actual server function. In other words, all of the
client-stub functions have APIs that differ from the server functions. To make the client-stub
functions have the same APIs as the original server functions, the user must implement wrapper
functions for the client-stub functions.
RPCGEN outputs definitions of the server ID and server version to <config file>_public.h.
Applications that call client-stub functions and the server-initialization function must thus include
<config file>_public.h so that the server ID and version are specified.
If <config file>_public.h for the client and server are from different generations, the RPC library
treats any RPC call as an error.

Description:
RPCGEN creates the following client-initialization function in <config file>_clnt.c as the
standard:
INT32 rpcclnt_<server name>_init(UINT32 __ulRPCServerID, UINT32
__ulRPCServerVersion );
If the CLNT_NOINIT statement is present, RPCGEN will not create the client-initialization
function. Use CLNT_NOINIT when the client-initialization function is provided as part of the
application. Also refer to section 8.6, Client-Initialization Function.

CLNT_NOSHUTDOWN
Format:
CLNT_NOSHUTDOWN;
Description:
RPCGEN creates the following client-shutdown function in <config file>_clnt.c as the standard:
INT32 rpcclnt_<server name>_shutdown(UINT32 __ulRPCServerID, UINT32
__ulRPCServerVersion );
If the CLNT_NOSHUTDOWN statement is present, RPCGEN will not create the client-shutdown
function. Use CLNT_NOSHUTDOWN when the client-shutdown function is provided as part of
the application.
The client-shutdown function generated by RPCGEN calls rpc_disconnect() to disconnect the
client from the server. Although rpc_disconnect() generally allows specification of a callback
function to be executed at the time the client is disconnected from the server, no callback function
is specifiable for the client-shutdown function generated by RPCGEN. If you wish to use a
callback function, specify CLNT_NOSHUTDOWN and implement the client-shutdown function
on the user side.
In the current HI7200/MP specification, a callback function is ignored even if one has been
specified for rpc_disconnect().
Also refer to section 8.7, Client-Shutdown Function.
Example:

Description:
RPCGEN creates the following code in <config file>_clnt.c to facilitate saving of the return values
of RPC calls (rpc_call() or rpc_call_copycbk()) and outputs the API of *rpc_retval_adr() in
<config file>_clnt.h.
*rpc_retval_adr() = rpc_call(...);
rpc_retval_adr() must be implemented by the user. If this definition is omitted, the following code,
which discards the return value of an RPC call, will be created.
rpc_call(...);
For how to implement rpc_retval_adr(), refer to section 8.8, rpc_retval_adr().

Section 6 Definitions of Server Functions
Without the REF specification, the data indicated by the pointer variable specified with PTR, STR,
or ARY are transferred. The transferred pointer points to a different area from that before the
transfer.
With the REF specification, the pointer variable is transferred. In this case, the pointer points to
the same area even after the transfer.
Note:
When the device in use does not provide a facility for cache-snooping between the CPU cores (as
is the case for the SH2A-DUAL etc.), the server parameter area must be allocated in a non-
cacheable area.
Example:
Specification of a server function

COUNT (Number of Elements in an Array)
Description:
When ARY is used, it must be followed by a definition of COUNT, which indicates the number of
elements in the array to be passed between the client and the server.
(1) When the input/output keyword selected for ARY is IN
In this case, a parameter specification that includes ARY must be followed by a single definition
of COUNT to indicate the number of elements in the array.
<parameter including ARY>,<definition of COUNT>
COUNT is an expression that specifies the number of elements in the array to be passed from the
client to the server.
RPCGEN creates client-stub code that makes an RPC call after setting the size of an input IOVEC
structure by using an expression of the kind specified in figure 6.2. This must be taken into
account when COUNT is defined. For example, the expression for COUNT must not contain any
variables that hold the return value of a function. Figures 6.2 and 6.3 show the code for example 5
(without SVR_AUTH) of the examples introduced following the figures.
int func (struct INF * inf, struct ST * ptr )
{
IOVEC __input[2];
...
__input[ __ulInputParamCount ].pBaseAddress = (UINT8 *)(inf);
__input[ __ulInputParamCount++ ].ulSize
= sizeof(*inf);
...
if (((UINT32)(inf->count)) > 0UL)
{
__input[ __ulInputParamCount ].pBaseAddress = (UINT8 *)(ptr);
__input[ __ulInputParamCount++ ].ulSize = sizeof(*ptr) * ((UINT32)(inf->count));
}

of elements in the array to be actually output by the server. This value must be less than or equal
to that specified for the first COUNT.
RPCGEN creates client-stub code that makes an RPC call after setting the size of an input IOVEC
structure by using an expression of the kind specified in figure 6.4. RPCGEN also creates server-
stub code that makes a server-function call before setting the size of an output IOVEC structure by
using an expression of the kind specified in figure 6.5. This must be taken into account in defining
the first and second COUNT. For example, an expression for the first COUNT must not contain
any variables that hold the return value of a function. Figures 6.4 and 6.5 show the code for
example 8 (without SVR_AUTH) of the examples introduced following the figures.

(3) When the input/output keyword selected for ARY is INOUT
In this case, a parameter specification that includes ARY must be followed by two definitions of
COUNT to indicate the number of elements in the array.
<parameter including ARY>,<definition of first COUNT>,
<definition of second COUNT>
The first COUNT is the COUNT keyword followed by an expression that specifies the number of
elements in the array to be passed from the client to the server.
The second COUNT is the COUNT keyword followed by an expression that specifies the number
of elements in the array to be actually output by the server. This value must be less than or equal
to that specified for the first COUNT.
RPCGEN creates client-stub code that makes an RPC call after setting the size of an input IOVEC
structure by using an expression of the kind specified in figure 6.6. RPCGEN also creates server-
stub code that makes a server-function call before setting the size of an output IOVEC structure by
using an expression of the kind specified in figure 6.7. This must be taken into account in defining
the first and second COUNT. For example, an expression for the first COUNT must not contain
any variables that hold the return value of a function. Figures 6.6 and 6.7 show the code for
example 8 (without SVR_AUTH) of the examples introduced following the figures.

Example:
Specification of a server function
int func(int par);
The function takes par as an input and returns a value of type int. RPCGEN will not create a

name. Use SVRFUNC when the name of a function as called by the client does not match the
name of the function as called by the server.
SVRFUNC cannot be used with SVRSTUB.
Example:
Specification of a server function
int func(int par);
The function takes par as an input and returns a value of type int. func on the server, however, is
named func_main.

Description:
The client makes RPC calls in asynchronous mode. When UNACK is not used, RPC calls are
made in synchronous mode.
UNACK cannot be used with CLNTSTUB.
Note:
When UNACK is used, the return value of the server function must be of type void and the
input/output keyword for parameters must be IN.

CLNTCOPYCBK (RPC Call by rpc_call_copycbk())
Format:
[CLNTCOPYCBK]<function 1> <function 2>
Description:
RPC calls are started by rpc_call_copycbk(). <function 1> and <function 2> are copy callback
functions specified in rpc_call_copycbk(). Specification of the two callback functions is
mandatory.
The prototype for the callback functions must conform with the RPC specifications and has to be
declared in a file included by the client stub.
Example:
Specification of a server function
int func(struct ST *ptr);
ptr is an array for output and has 10 elements, all of which are output by func. copy1() is used
for transfer from the client to the server while copy2() is used for transfer from the server to the
client.

Section 7 Server Functions Not Supported by RPCGEN
Section 7 Server Functions Not Supported by RPCGEN
This section gives the types of functions not supported by RPCGEN. If a server function you are
using falls under the definitions in this section, use SVRSTUB or CLNTSTUB so that RPCGEN
will not create a server or client stub for the server function. A substitute server or client stub must
be implemented by the user.
7.1
Parameter
RPCGEN is not capable of correctly creating a client or server stub for server functions that have
parameters of the following types.
(1) Parameters with data types of undefined size
RPCGEN cannot handle parameters with data types that have undefined size. When such a
parameter is a pointer, however, using REF allows the creation of stub code for passing of the
pointer itself.
Example:
Specification of a server function
int func(void *par);
The function takes ptr, a pointer to data of undefined size, as an input and returns an int-type
value.
Definition of the server function
int ret = func([IN PTR]void *par);
In this case, an error will occur in compilation of the client stub.
int ret = func([IN REF PTR]void *par);
In this case, code to pass the value of par to the server will be created.

REJ10J1822-0101
Section 7 Server Functions Not Supported by RPCGEN
(2) Multiple-level pointers
RPCGEN only recognizes the first level of multiple-level pointers.
Example:
Specification of a server function
int func(int **ptr);
The function takes ptr, a pointer to a pointer to int-type data, as an input.
Definition of the server function
int ret = func([IN PTR] int **ptr);
In this case, RPCGEN creates code to transfer *ptr from the client to the server. *ptr is a pointer
to the target int-type data, but this data (**ptr) will not be transferred.
(3) Function pointer
RPCGEN does not support server functions whose parameters are pointers to functions.

Section 7 Server Functions Not Supported by RPCGEN
7.2
Return Value
(1) Pointer
If a function returns a pointer-type value, this return value indicates an address in the server.
RPCGEN does not create any code to transfer the data indicated by the pointer from the server to
the client.
Example:
Specification of a server function
int *func(int par);
The return value is a pointer to int-type data.
Definition of the server function
int *ret = func([IN DFLT]int par);
In this case, ret is a pointer to int-type data returned within the server by the server function.

Client-Stub Functions Generated by RPCGEN
The client-stub functions are called by the client application.
This section gives the specifications for the client-stub functions generated by RPCGEN. The
client-stub functions must be called in accord with the definitions in these specifications. If
CLNTSTUB is used to prevent creation of client-stub functions, the user must implement client-
stub functions in accord with the specifications.
For details on SVR_AUTH, refer to section 5.5.8, SVR_AUTH.
(1) When SVR_AUTH has not been specified
Each of the client-stub functions has the same API as the actual server function. RPCGEN outputs
the client-stub functions themselves to <config file>_clnt.c but does not output prototype
declarations. Prepare a header file with the required prototype declarations and specify this header
file in the definition of CLNT_INCFILE or GLOBAL_INCFILE.
Example:
Contents of a config file
SVR_NAME{ EXAMPLE };
SVR_ID{ 1 };
SVR_VERSION{ 2 };
// SVR_AUTH;
RPC_FUNC{
int ret = func1([IN DFLT]int par1, [IN DFLT]int par2);
func2([OUT PTR]struct ST *ptr);
};
Specification of a client-stub function

Section 8 Application Interface
(2) When SVR_AUTH has been specified
Each of the client-stub functions has a different API from the corresponding actual server function
and the server ID and server version information are added as parameters. RPCGEN outputs the
client-stub functions themselves to <config file>_clnt.c and the prototype declarations to <config
file>_clnt.h.
The name of each client-stub function takes the form rpcclnt_<server name>_<server function
name>. <Server name> refers to the server name defined with SVR_NAME and <server function
name> refers to server function names defined between the braces {} of RPC_FUNC.
The first and second parameters of the client-stub functions are the server ID and server version,
respectively. The names of the parameters are fixed to __ulID and __ulVers. The third and
subsequent parameters are the first and subsequent parameters of the actual server function and
their names are those defined in RPC_FUNC.
Example:
Contents of a config file
SVR_NAME{ EXAMPLE };
SVR_ID{ 1 };
SVR_VERSION{ 2 };
SVR_AUTH;
RPC_FUNC{
int ret = func1([IN DFLT]int par1, [IN DFLT]int par2);
func2([OUT PTR]struct ST *ptr);
};
Specification of a client-stub function
int rpcclnt_EXAMPLE_func1(UINT32 __ulID, UINT32 __ulVers, int par1, int
par2);

Server-Stub Functions Generated by RPCGEN
RPCGEN outputs the server-stub functions themselves to <config file>_svr.c and the prototype

The name of each server-stub function takes the form rpcsvr_<server name>_<server function
name>. <Server name> refers to the server name defined with SVR_NAME and <server function
name> refers to server function names defined between the braces {} of RPC_FUNC.
Since the server-stub functions are called from within the RPC library, the user usually does not
need to recognize the APIs of the server-stub functions output by RPCGEN. If SVRSTUB is used
to prevent creation of the server-stub functions, however, the user must implement the server-stub
functions in accord with the specifications.
Example:
Contents of a config file

The server-initialization function is called by the server application and starts up the server by
using rpc_start_server() or rpc_start_server_with_paramarea().
When SVR_NOINIT has not been specified, RPCGEN generates a server-initialization function
rpcsvr_<server name>_init. RPCGEN outputs the server-initialization function itself to <config
file>_svr.c and the prototype declaration to <config file>_svr.h.
<Server name> refers to the server name defined with SVR_NAME.
When SVR_NOINIT has been specified, RPCGEN does not generate a server-initialization
function. The server-initialization function must be provided by the user if one is required.
The specification of the server-initialization function generated by RPCGEN is as follows.
•
C-language API
INT32 rpcsvr_<server name>_init( rpc_svr_config *__config);
•
•
Return value
The return value of rpc_start_server() or rpc_start_server_with_paramarea()
Parameter: __config
The definition of an rpc_svr_config structure is given below. Each of the members has the
same meaning as that of the rpc_server_info structure.
typedef struct {
UINT32 ulRPCServerID;
UINT32 ulRPCServerVersion;
UINT32 ServerStubTaskPriority;
UINT32 ulStubStackSize;
UINT32 ulMaxParamAreaSize;
void *pUserDefinedData;
} rpc_svr_config;

Section 8 Application Interface
•
Specification
The server is started up by calling rpc_start_server() when SVR_STATIC has not been
specified or rpc_start_server_with_paramarea() when SVR_STATIC has been specified.
When SVR_AUTH has not been specified, however, the definitions of server ID and version in
__config. UlRPCServerID and __config. UlRPCServerVersion are ignored. Instead, the
macros RPCSVR_ID_<server name> and RPCSVR_VERS_<server name> output to <config
file>_public.h are taken as the server ID and version in starting up the server.
8.4
Server-Stub Function Table
The server-stub function table is rpc_server_info.ServerStubList, the table defined by
rpc_start_server() or rpc_start_server_with_paramarea() called by the server-initialization
function.
(1) With neither SVR_NOSTUBTBL nor SVR_NOINIT
RPCGEN generates the server-initialization function and server-stub function table. Only the
server-initialization function generated by RPCGEN looks up the server-stub function table. Thus
RPCGEN outputs the server-stub function table as static data to <config file>_svr.c.
(2) Without SVR_NOSTUBTBL and with SVR_NOINIT
RPCGEN does not generate the server-initialization function but does generate the server-stub
function table. RPCGEN outputs the server-stub function table in the form given below to <config
file>_svr.c. The server-initialization function provided in the application must look up the server-
stub function table to call rpc_start_server() or rpc_start_server_with_paramarea().
UINT32 (* const __rpcsvr_<server name>
_StubTable[])(rpc_server_stub_info *) =
{
<server-stub function name>,
<server-stub function name>,
};
<Server name> refers to the server name defined with SVR_NAME.

Section 8 Application Interface
(3) With SVR_NOSTUBTBL and without SVR_NOINIT
RPCGEN does not generate the server-stub function table but does generate the server-
initialization function. RPCGEN assumes that the server-stub function table shown below is
provided in the application and outputs the server-initialization function, which externally refers to
the table, to <config file>_svr.c.
UINT32 (* const __rpcsvr_<server name>_StubTable[])
(rpc_server_stub_info *) =
{
<server-stub function name>,
<server-stub function name>,
};
<Server name> refers to the server name defined with SVR_NAME.
(4) With SVR_NOSTUBTBL and SVR_NOINIT
RPCGEN generates neither a server-initialization function nor a server-stub function table, so they
must be provided in the application.

Server-Shutdown Function
The server-shutdown function is called by the server application and stops the server by using
rpc_stop_server().
When SVR_NOSHUTDOWN has not been specified, RPCGEN generates a server-shutdown
function rpcsvr_<server name>_shutdown. RPCGEN outputs the server-shutdown function itself
to <config file>_svr.c and the prototype declaration to <config file>_svr.h.
<Server name> refers to the server name defined with SVR_NAME.
When SVR_NOSHUTDOWN has been specified, RPCGEN does not generate a server-shutdown
function. The server-shutdown function must be provided by the user if one is required.
The specification of the server-shutdown function generated by RPCGEN is as follows.
•
C-language API
INT32 rpcsvr_<server name>_shutdown(UINT32 __ulServerID, UINT32
__ulServerVersion);
•
•
Return value
The return value of rpc_stop_server()
Parameter: __ulServerID and __ulServerVersion
These parameters indicate the server ID and server version, respectively. When SVR_AUTH
has not been specified, however, the server ID and server version are ignored. Instead, the
macros RPCSVR_ID_<server name> and RPCSVR_VERS_<server name> output to <config
file>_public.h are taken as the server ID and server version in stopping the server.
•
Specification
The server is stopped by calling rpc_stop_server() and no callback function is specifiable for
the server-shutdown function. If you wish to use a callback function, specify
SVR_NOSHUTDOWN and implement the server-shutdown function on the user side.

Client-Initialization Function
The client-initialization function is called by the client application and initiates connection to the
server by using rpc_connect().
When CLNT_NOINIT has not been specified, RPCGEN generates a client-initialization function
rpcclnt_<server name>_init. RPCGEN outputs the client-initialization function itself to <config
file>_clnt.c and the prototype declaration to <config file>_clnt.h.
<Server name> refers to the server name defined with SVR_NAME.
When CLNT_NOINIT has been specified, RPCGEN does not generate a client-initialization
function. The client-initialization function must be provided by the user if one is required.
The specification of the client-initialization function generated by RPCGEN is as follows.
•
C-language API
INT32 rpcclnt_<server name>_init(UINT32 __ulRPCServerID, UINT32
__ulRPCServerVersion);
•
•
Return value
The return value of rpc_connect()
Parameter: __ulRPCServerID and __ulRPCServerVersion
These parameters indicate the server ID and server version, respectively. When SVR_AUTH
has not been specified, however, the server ID and server version are ignored. Instead, the
macros RPCSVR_ID_<server name> and RPCSVR_VERS_<server name> output to <config

•
Specification
Connection to the server is initiated by using rpc_connect().

function. The client-shutdown function must be provided by the user if one is required.
The specification of the client-shutdown function generated by RPCGEN is as follows.
•
C-language API
INT32 rpcclnt_<server name>_shutdown(UINT32 __ulRPCServerID, UINT32
__ulRPCServerVersion);
•
•
Return value
The return value of rpc_disconnect()
Parameter: __ulRPCServerID and __ulRPCServerVersion
These parameters indicate the server ID and server version, respectively. When SVR_AUTH
has not been specified, however, the server ID and server version are ignored. Instead, the
macros RPCSVR_ID_<server name> and RPCSVR_VERS_<server name> output to <config
file>_public.h are taken as the server ID and server version in terminating a connection to the
server.
•
Specification
Connection to the server is terminated by using rpc_disconnect() and no callback function is
specifiable for the client-shutdown function. In the current HI7200/MP specification,
rpc_disconnect() handles no processing other than terminating the connection to the server.

Local Variables Used in the Source Code Created by RPCGEN
In the source code of the client and server stubs, the names of local variables start with two
underscores ("__"). In the client and server stubs, on the other hand, RPCGEN uses the parameter
names specified in the definitions of server functions. For this reason, the parameter names
specified in the definitions of server functions must not start with two underscores ("__").

Section 9 Notes
Section 9 Notes
(1) Check that the source program generated by RPCGEN works as intended.
We do not guarantee the operation of the program generated by RPCGEN. Be sure to check that
the program works as you intended.
RPCGEN does not report errors except in cases where a fatal error has been detected (i.e. when
continuing with current processing is impossible).
(2) Do not modify the contents of the files generated by RPCGEN.
Even if the contents of the source files generated by RPCGEN are not as you expected, do not
modify the files manually. This is because files that have been manually modified by the user may
be overwritten when RPCGEN is re-executed. Instead of manually correcting the generated files,
check and correct the contents of config files.

Section 10 Error Messages
Section 10 Error Messages
RPCGEN shows an error message and terminates processing only when it has detected a fatal
error (i.e. when continuing with the current processing is impossible). In other words, RPCGEN
behaves as if it has successfully completed code generation in many cases where it has not in fact
done so.
Cases in which no errors will be detected:
Note: “->” in the list below indicates a behavior in the current implementation. The behavior may
be changed in a future implementation.
•
•
•
•
•
A specific keyword is used multiple times.
-> The first instance of the keyword to be found is valid.
A server function with a specific name is declared multiple times.
-> An error will be reported on compilation of the generated stub.
An invalid keyword is specified.
-> This is simply ignored.
SVR_ID (server ID) is a value with size exceeding 4 bytes.
-> An error will be reported on compilation of the file to include rpc_public.h.
A parameter for which PTR has been specified is not of the pointer type.
-> RPC calls will lead to abnormal operation such as CPU exceptions.

This section introduces samples of the code in a config file and the corresponding output files. To
create these samples, we have used the C standard library functions and the HI7200/MP service
calls listed in table 11.1. This is simply because we have assumed that most users will understand
these functions, not because the functions should necessarily be distributed by the RPC facility.
