NAME

6       getrpcport - get RPC port number
7

LIBRARY

9       Standard C library (libc, -lc)
10

SYNOPSIS

12       #include <rpc/rpc.h>
13
14       int getrpcport(const char *host, unsigned long prognum,
15                      unsigned long versnum, unsigned int proto);
16

DESCRIPTION

18       getrpcport()  returns  the  port  number for version versnum of the RPC
19       program prognum running on host and using protocol proto.  It returns 0
20       if  it  cannot contact the portmapper, or if prognum is not registered.
21       If prognum is registered but not with version versnum,  it  will  still
22       return  a port number (for some version of the program) indicating that
23       the program is indeed registered.  The version  mismatch  will  be  de‐
24       tected upon the first call to the service.
