I would concur with the comments of talexb above - I have found Inline::C to make incorporating C and Perl code together incredibly easy.

The only thing which I would add to talexb's post is a few links for further information:

• the Inline C Cookbook,
• the Inline C Reference, and
• the Inline home.

 

perl -e 'print+unpack("N",pack("B32","00000000000000000000000111011110")),"\n"'
