GETRPCPORT(3) Linux Programmer's Manual GETRPCPORT(3)
NAME
getrpcport - get RPC port number
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 detected upon the first call to the service.
