NAME
====

Sys::Hostname - Implement Perl 5's Sys::Hostname core module

SYNOPSIS
========

    use Sys::Hostname;
    $host = hostname;

DESCRIPTION
===========

Attempts several methods of getting the system hostname and then caches the result. It tries the first available of the C library's gethostname(), uname(2), syscall(SYS_gethostname), `hostname`, `uname -n`, and the file /com/host. If all that fails it dies.

All NULs, returns, and newlines are removed from the result.

PORTING CAVEATS
===============

At present, only `hostname`, `uname -n` and /com/host are attempted before dieing.
