This module provides a C API for XS modules to hook into the callbacks of
PL_check .
the ExtUtils::Depends manpage is used to export all functions for other XS modules to
use. Include the following in your Makefile.PL:
my $pkg = ExtUtils::Depends->new('Your::XSModule', 'B::Hooks::OP::Check');
WriteMakefile(
... # your normal makefile flags
$pkg->get_makefile_vars,
);
Your XS module can now include hook_op_check.h .
Type that callbacks need to implement.
Type to identify a callback.
Register the callback cb to be called after the PL_check function for
opcodes of the given type . user_data will be passed to the callback as
the last argument. Returns an id that can be used to remove the callback later
on.
Remove the callback identified by id . Returns the user_data that the callback had.
Bugs may be submitted through the RT bug tracker
(or bug-B-Hooks-OP-Check@rt.cpan.org).
