getrpcport(3)           Library Functions Manual           getrpcport(3)

NAME top

       getrpcport - get RPC port number

LIBRARY top

       Standard C library (libc, -lc)

SYNOPSIS top

       #include <rpc/rpc.h>

       int getrpcport(const char *host, unsigned long prognum,
                      unsigned long versnum, unsigned int proto);

DESCRIPTION top

       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.
