NAME B::Hooks::OP::Check - Wrap OP check callbacks SYNOPSIS # include "hook_op_check.h" STATIC OP *my_const_check_op (pTHX_ OP *op, void *user_data) { /* ... */ return op; } void setup () CODE: hook_op_check (OP_CONST, my_const_check_op, NULL); DESCRIPTION This module provides a c api for XS modules to hook into the callbacks of "PL_check". ExtUtils::Depends 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". TYPES typedef OP *(*hook_op_check_cb) (pTHX_ OP *, void *); Type that callbacks need to implement. FUNCTIONS void hook_op_check (opcode type, hook_op_check_cb cb, void *user_data) Register the callback "cb" to be called after the "PL_check" function for opcodes of the given "type".
