NAME
       B::Hooks::OP::PPAddr - Hook into	opcode execution

VERSION
       version 0.06

SYNOPSIS
	   #include "hook_op_check.h"
	   #include "hook_op_ppaddr.h"

	   STATIC OP *
	   execute_entereval (pTHX_ OP *op, void *user_data) {
	       ...
	   }

	   STATIC OP *
	   check_entereval (pTHX_ OP *op, void *user_data) {
	       hook_op_ppaddr (op, execute_entereval, NULL);
	   }

	   hook_op_check (OP_ENTEREVAL,	check_entereval, NULL);

DESCRIPTION
       This module provides a C	API for	XS modules to hook into	the execution
       of perl opcodes.

       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::PPAddr');
	   WriteMakefile(
	       ... # your normal makefile flags
	       $pkg->get_makefile_vars,
	   );

       Your XS module can now include "hook_op_ppaddr.h".

TYPES
   OP
	   typedef OP *(*hook_op_ppaddr_cb_t) (pTHX_ OP	*, void	*user_data)

       Type that callbacks need	to implement.

FUNCTIONS
   hook_op_ppaddr
	   void	hook_op_ppaddr (OP *op,	hook_op_ppaddr_cb_t cb,	void *user_data)

       Replace the function to execute "op" with the callback "cb".
       "user_data" will	be passed to the callback as the last argument.

   hook_op_ppaddr_around
	   void	hook_op_ppaddr_around (OP *op, hook_op_ppaddr_cb_t before, hook_op_ppaddr_cb_t after, void *user_data)

       Register	the callbacks "before" and "after" to be called	before and
       after the execution of "op". "user_data"	will be	passed to the callback
       as the last argument.
