getrpcport(3) Library Functions Manual getrpcport(3)
NAME
getrpcport - get RPC port number
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <rpc/rpc.h>
int getrpcport(const char *host, unsigned long prognum,
unsigned long versnum, unsigned int proto);
DESCRIPTION
getrpcport() returns the port number for version versnum of the RPC
program prognum running on host and using protocol proto. It returns 0
if it cannot contact the portmapper, or if prognum is not registered.
If prognum is registered but not with version versnum, it will still
return a port number (for some version of the program) indicating that
the program is indeed registered. The version mismatch will be de-
tected upon the first call to the service.
