Compile-Time ANSI C-compliant Code

rpcgen can also produce output that is compatible with ANSI C. This feature is selected with the -C compile flag and is most often used with the -N flag, described in Compile-Time C-style Mode.

The add.x example of the server template is generated by the rpcgen -N -C -Ss -o add_server_template.c add.x command:

Note that on the C++ 3.0 server, remote procedure names require an _svc suffix. In the following example, the add.x template and the -C compile flag produce the client side add_1 and the server stub add_1_svc.

Example 3–22 rpcgen ANSI C Server Template

/*
 * This is a template. Use it to
 * develop your own functions.
 */
#include <c_varieties.h>
#include "add.h"
 
int *
add_1_svc(int arg1, int arg2,
					struct svc_req *rqstp)
{
	static int result;
	/*
	 * insert server code here
	 */
	return(&result);
}

This output conforms to the syntax requirements and structure of ANSI C. The header files that are generated when this option is invoked can be used with ANSI C or with C++.
