NAME

       getrpcport - get RPC port number

SYNOPSIS

       #include <rpc/rpc.h>

       int getrpcport(const char *host, unsigned long prognum,
                      unsigned long versnum, unsigned 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.
