# NAME

Sys::Hostname - Try every conceivable way to get hostname

# SYNOPSIS

        use Sys::Hostname;
        my $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(), `$Config{aphostname}`, uname(2), syscall(SYS_gethostname), `hostname`, `uname -n`, and the file /com/host. If all that fails it "croak"s.

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