I know, we've filed a patent for it, wait for it, no, wait, ok, just 
kidding...  :-)

Not sure exactly what you want, but with the below I think it will be 
obvious how to do it.

void ioctl(int, unsigned long, char *) __attribute__((always_inline));
asm inline void ioctl(int fd, unsigned long m, char *buf) {
         movl    #42, 12($esp)
         movl    fd, 8($esp)
         movl    m, 4($esp)
         movl    buf, ($esp)
         call    _xioctl
         xorl    $eax, $eax
         leave
         ret
}

main() {
   ioctl (0, 0, "hi");
}

though, you may need nakky and to spell the inline slightly 
differently, the above uses CW style assembly.
