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 detected upon the first call to the service.
