The pmap_getport() call returns the port number associated with the remote program (prognum), the version (versnum), and the transport protocol (protocol).

Syntax

#include <rpc\rpc.h>

u_short
pmap_getport(addr, prognum, versnum, protocol)
struct sockaddr_in *addr;
u_long prognum;
u_long versnum;
u_long protocol;

Parameters

addr

Pointer to the internet address of the remote host. prognum

Program number to be mapped. versnum
