C-DynaLib is a Perl module that allows Perl programs to call C functions in dynamic libraries. It is useful for testing library functions, writing simple programs without the bother of XS, and generating C function pointers that call Perl code. If you have a C compiler that Perl supports, you will get better results by writing XSubs than by using this module.
