Pike v8.1 release 6

Module NetUtils

Description

Various networking-related utility functions.


Variable ANY

string NetUtils.ANY

Description

Returns either 0 or "::" depending on whether or not this computer has IPv6 support.

The intent is to use this when binding addresses, like port->bind(portno,callback,NetUtils.ANY) to get ipv6 support if present.

The reason for the existence of this function is that using "::" on a computer that does not actually have any ipv6 addresses (and thus no support for ipv6), at least on linux, causes the bind call to fail entirely.

Constant locality

constant NetUtils.locality

Description

Mapping from NetworkType to an integer between 0 and 10 that describes how local that type of network is.
