6 * This file should contain stubs for any of the TCP/IP functions perl5
7 * requires which are not supported by your TCP/IP stack. These stubs
8 * can attempt to emulate the routine in question, or can just return
9 * an error status or cause perl to die.
11 * This version is set up for perl5 with UCX (or emulation) via
12 * the DECCRTL or SOCKETSHR 0.9D.
