Something like

if ( ($iSockFD = socket (AF_INET, SOCK_STREAM,0) ) != 0) {
	print "Call to socket() failed: reason: " . strerror ($iSockFD) . "\n";
	exit();
}

That results in an "Unknown error 4294967293" message from strerror() in Linux kernel 2.2.16.. A "Unknown error: -3" in FreeBSD 4.0  -- no matter what user I am, this error occurs on both operating systems..

Read your local man page on socket(2). Most of the functions in the sockets extension return >= 0 on success and < 0 on error.

Reclassified as a documentation problem.

Docs writers: feel free to bug me on the semantics of the functions in the module and such :)

This behaviour has already been documented, including the reference to the socket(2) man page.
