This is an excerpt from the latest version perlfaq8.pod, which
comes with the standard Perl distribution. These postings aim to
reduce the number of repeated questions as well as allow the community
to review and update the answers. The latest version of the complete
perlfaq is at http://faq.perl.org .

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".

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.

If you'd like to help maintain the perlfaq, see the details in
perlfaq.pod.
