pmap_getmaps()

The pmap_getmaps() call returns a list of current program-to-port mappings on a specified remote host's Portmapper.

Syntax

#include <rpc\rpc.h>

struct pmaplist *
pmap_getmaps(addr)
struct sockaddr_in *addr;

Parameters

addr

Pointer to the internet address of the remote host.

Description

The pmap_getmaps() call returns a list of current program-to-port mappings on the remote host's Portmapper specified by addr.

Examples

struct hostent *hp;struct sockaddr_in pmapper_addr;
struct pmaplist *my_pmaplist = NULL;

if ((hp = gethostbyname("PMAP_HOST") == NULL)
  {
   fprintf(stderr,"Can't get address for %s\n","PMAP_HOST");
   exit (-1);
  }

bcopy(hp->h_addr, (caddr_t)&pmapper_addr.sin_addr.s_addr, hp->h_length);
pmapper_addr.sin_family = AF_INET;
pmapper_addr.sin_port = 0;

/*
