NAME
       getrpcport - get RPC port number

SYNOPSIS
       int getrpcport(char *host, int prognum, int versnum, int proto);

DESCRIPTION
       getrpcport()  returns  the port number for version versnum of the RPC program prognum run-
       ning 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.

CONFORMING TO
       Not in POSIX.1-2001.  Present on the BSDs, Solaris, and many other systems.
