Sure, we use SWIG (http://www.swig.org/) which basically creates a Perl
wrapper (.pm) around a .so and you specify which methods to make available
to the .pm. It has a few problems (doesn't handle certain overloaded methods
very well - eg when the only difference is the data type of parameter
expected) but is quite decent

> 2. anyone reccomend a C book to use while learning.

"The C Programming Language" 2nd Ed by Brian Kernighan and Dennis Ritchie is
an excellent place to start I think :-)
