getrpcport()

Format

#include <rpc.h>
u_short
getrpcport(host, prognum, versnum, protocol)
char *host;
u_long prognum;
u_long versnum;
int protocol;

Parameters

host: Specifies the pointer to the name of the foreign host.
prognum: Specifies the program number to be mapped.
versnum: Specifies the version number of the program to be mapped.
protocol: Specifies the transport protocol used by the program (IPPROTO_TCP or IPPROTO_UDP).

Usage

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

Return codes

The value 1 indicates that the mapping does not exist or that the remote portmap could not be contacted. If portmapper cannot be contacted, rpc_createerr contains the RPC status.
