GETRPCPORT(3) FreeBSD Library Functions Manual GETRPCPORT(3)
NAME
getrpcport - get RPC port number
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
int
getrpcport(char *host, int prognum, int versnum, int proto);
DESCRIPTION
The getrpcport() function 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.
