Devel::CallChecker makes some new features of the Perl 5.14.0 C API available to XS modules running on older versions of Perl. The features are centred around the function cv_set_call_checker, which allows XS code to attach a magical annotation to a Perl subroutine, resulting in resolvable calls to that subroutine being mutated at compile time by arbitrary C code. This module makes cv_set_call_checker and several supporting functions available. (It is possible to achieve the effect of cv_set_call_checker from XS code on much earlier Perl versions, but it is painful to achieve without the centralised facility.) Devel::CallCheckerprovides the implementation of the functions at runtime (on Perls where they are not provided by the core). It also, at compile time, supplies the C header file and link library which provide access to the functions. In normal use, "callchecker0_h" and "callchecker_linkable" should be called at build time (not authoring time) for the module that wishes to use the C functions.
