getrpcpor(3R)

NAME
     getrpcport - get RPC port number

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

NOTE
     To compile and link a program that calls this routine, follow the
     procedures for section (3R) routines as described in intro (3).
