7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas

products are not designed, manufactured or tested for applications or otherwise in systems the failure or

malfunction of which may cause a direct threat to human life or create a risk of human injury or which require

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.

REJ10J1822-0101

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.

3.2 Files Generated by RPCGEN

RPCGEN generates the files listed in table 3.1 in accord with the name of the config file.

Table 3.1 Files Generated by RPCGEN

Filename Description Definition of the File Location

<config file>_clnt.c Client-stub source file CLNTS option or

CLNT_SOURCEPATH in the config file

<config file>_clnt.h Client-stub header file

<config file>_private.h Internal header file for the

client stub

CLNTI option or CLNT_INCPATH in

the config file

<config file>_svr.c Server-stub source file SVRS option or SVR_SOURCEPATH

in the config file

<config file>_svr.h Server-stub header file SVRI option or SVR_INCPATH in the

config file

<config file>_public.h Header file for the client and

server stubs

PUBI option or PUB_INCPATH in the

config file

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 3 Functions and Files Generated by RPCGEN

Rev. 1.01 Mar. 17, 2008 Page 8 of 128

REJ10J1822-0101

(3) <config file>_private.h (internal header file for the client stub)

This is a header file included by <config file>_clnt.c only.

(4) <config file>_svr.c (server-stub source file)

This file contains the server-stub functions, server-initialization function, server-shutdown

function, and server-stub function table.

(5) <config file>_svr.h (server-stub header file)

This file contains definitions required for use of the server-initialization function and server-

shutdown function. The definitions include prototype declarations of the server-stub functions,

server-initialization function, and server-shutdown function.

(6) <config file>_public.h (header file for the client and server stubs)

This is a header file for the client and server applications. For details, refer to section 8.9, <config

file>_public.h.

REJ10J1822-0101

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.

4.2.1 PUBI

Format:

PUBI="<path>"

Description:

This option is used to specify the path for output of <config file>_public.h. If this option is used, a

definition of PUB_INCPATH in the config file is ignored.

Format:

CLNTS="<path>"

Description:

This option is used to specify the path for output of <config file>_clnt.c. If this option is used, a

definition of CLNT_SOURCEPATH in the config file is ignored.

4.2.3 CLNTI

Format:

CLNTI="<path>"

Description:

This option is used to specify the path for output of <config file>_clnt.h and

<config file>_private.h. If this option is used, a definition of CLNT_INCPATH in the config file

is ignored.
