8.20: How can I call my system's unique C functions from Perl?

    In most cases, you write an external module to do it--see the answer to
    "Where can I learn about linking C with Perl? [h2xs, xsubpp]". However,
    if the function is a system call, and your system supports syscall(),
    you can use the syscall function (documented in perlfunc).

    Remember to check the modules that came with your distribution, and CPAN
    as well---someone may already have written a module to do it. On
    Windows, try Win32::API. On Macs, try Mac::Carbon. If no module has an
    interface to the C function, you can inline a bit of C in your Perl
    source with Inline::C.
