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 . -------------------------------------------------------------------- 8.21: Where do I get the include files to do ioctl() or syscall()? Historically, these would be generated by the "h2ph" tool, part of the standard perl distribution. This program converts cpp(1) directives in C header files to files containing subroutine definitions, like &SYS_getitimer, which you can use as arguments to your functions. It doesn't work perfectly, but it usually gets most of the job done. Simple files like errno.h, syscall.h, and socket.h were fine, but the hard ones like ioctl.h nearly always need to be hand-edited. Here's how to install the *.ph files: 1. become super-user 2. cd /usr/include 3. h2ph *.h */*.h If your system supports dynamic loading, for reasons of portability and sanity you probably ought to use "h2xs" (also part of the standard perl distribution). This tool converts C header files to Perl extensions. See perlxstut for how to get started with "h2xs". If your system doesn't support dynamic loading, you still probably ought to use "h2xs". See perlxstut and ExtUtils::MakeMaker for more information (in brief, just use make perl instead of a plain make to rebuild perl with a new static extension). -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.
