Hello PHP'ers!

We wish to control a hardware device (a GPIB card) using a web
interface.  This device is normally controlled using either:

1. simple ioctl() calls to the linux kernel
2. by a higher level C-library which inturn calls these ioctl()s.

Does PHP support system calls like ioctl()? I was unable to find it in
the PHP manual.  Or even better, can I use the high-level C library
functions for this card from within PHP, without _too_ much of hacking
into the internals of PHP ?

best regards,
