getrpcport(3) — Subroutines

NAME

getrpcport − get RPC port number

SYNOPSIS

#include <rpc/rpc.h>
int getrpcport(
        char ∗host,
        int prognam,
        int versnum,
        int proto );

DESCRIPTION

The getrpcport() routine returns the port number for version versnum of the RPC program prognam running on host and using protocol proto.

It returns 0 if it cannot contact the portmapper or if prognam is not registered. If prognam is registered but not with version versnum, the routine will return the port number of the last registered prognam, proto pair.

RETURN VALUES

Upon successful completion, a port number is returned; otherwise, 0 is returned to indicate that either the portmapper could not be contacted or the program is not registered.

ERRORS

None
