svc_unreg Subroutine

Purpose

Unregisters the program number and version number with the remote procedure call (RPC) service package.

Library

Network Services Library (libnsl.a)

Syntax

#include <rpc/rpc.h>

void  svc_unreg(prog ,vers)
const rpcprog_t prog;
const rpcvers_t vers;

Description

This subroutine is an expert-level API for transport-independent remote procedure calls (TI_PRC). This subroutine removes the mapping to network address from the RPC service package. The subroutine also unregisters the program number and version number from the dispatch subroutine with the RPC service package. When the subroutine is called, the whole service that is identified by the program and version gets unregistered.

Parameters

Examples

#include <stdlib.h>
#include <rpc/rpc.h>
#include <netconfig.h>

#define PROG 0x3fffffffL
#define VERS 0x1L

main()
{

  SVCXPRT *svc_handle;    /* service handle */
  struct netconfig *nconf;

  /* Get transport type and create RPC service handle. */   
 
  /* Register dispatch routine for prog and vers with RPCBIND service */

  If(svc_reg(svc_handle, PROG, VERS, sample_dispatch,nconf) == 0)
  {
    sprintf(stdout,"Error in svc_reg!");
    exit(EXIT_FAILURE);
  }
  
  /* Unregister the service with given prog and vers */
  svc_unreg(PROG, VERS);

  return 0;
}
