NAME
B::Hooks::OP::PPAddr - Hook into opcode executionSYNOPSIS
#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
typedef OP *(*hook_op_ppaddr_cb_t) (pTHX_ OP *, void *user_data)
Type that callbacks need to implement.FUNCTIONS
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.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.SEE ALSO
