How to use ioctl in perl

sanju_631 has asked for the wisdom of the Perl Monks concerning the following question:

Hi ! I have problems using ioctl in perl on linux platform. i have written a perl script

.........test.pl.......
#!/usr/bin/perl
require 'sys/ioctl.ph'

..........

this itself on running is giving error

# ./test.pl
Scalar found where operator expected at (eval 273) line 1, near "'int'
+  $__val"
        (Missing operator before   $__val?)
#

the sys/ioctl.ph file is located in
/usr/lib/perl5/vendor_perl/5.8.3/ppc-linux-thread-multi on my system .
@INC contains: /usr/lib/perl5/5.8.3/ppc-linux-thread-multi /usr/lib/perl5/5.8.3 /usr/lib/perl5/site_perl/5.8.3/ppc-linux-thread-multi /usr/lib/perl5/site_perl/5.8.3 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.3/ppc-linux-thread-multi ********** /usr/lib/perl5/vendor_perl/5.8.3 /usr/lib/perl5/vendor_perl

stars in abouve shows that sys/ioctl.ph is in proper path to be included by require command. But even then why i m getting error shown above???
Please reply soon..
Thanks..
Sanju

Uh, perhaps a little background would be helpful Before you post...

Ah. The light bulb went off. I haven't seen the .ph extension before. It's an output from the command h2ph

Here is a snipped from the man on h2ph.

h2ph converts any C header files specified to the corresponding Perl
       header file format.  It is most easily run while in /usr/includ
+e:
 
               cd /usr/include; h2ph * sys/*
 
       or
 
               cd /usr/include; h2ph * sys/* arpa/* netinet/*
 
       or
 
               cd /usr/include; h2ph -r -l .
 
       The output files are placed in the hierarchy rooted at Perl's a
+rchitec-
       ture dependent library directory.  You can specify a different 
+hierar-
       chy with a -d switch.
 
       If run with no arguments, filters standard input to standard ou
+tput.

I haven't used h2ph before. This probably hasn't been run on your perl install so that's why file you are trying to require is missing. So you'll need to run this command on the headers that you're interested in using. Pretty low level stuff.

Again, a description of what you are trying to do would probably net you more feedback on Perlmonks.

I posted a handmade substitute for ioctl.ph at Linux ioctl command module. It is a close transcription of Linux 2.4 ioctl.h in perl.
