=head1 NAME
B::Hooks::OP::PPAddr - Hook into opcode execution
=head1 VERSION
version 0.05
=head1 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);
=head1 DESCRIPTION
This module provides a C API for XS modules to hook into the execution of perl
opcodes.
L<ExtUtils::Depends> is used to export all functions for other XS modules to
use. Include the following in your F<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 C<hook_op_ppaddr.h>.
=head1 TYPES
=head2 OP
typedef OP *(*hook_op_ppaddr_cb_t) (pTHX_ OP *, void *user_data)
Type that callbacks need to implement.
=head1 FUNCTIONS
=head2 hook_op_ppaddr
void hook_op_ppaddr (OP *op, hook_op_ppaddr_cb_t cb, void *user_data)
Replace the function to execute C<op> with the callback C<cb>. C<user_data>
will be passed to the callback as the last argument.
=head2 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 C<before> and C<after> to be called before and after the
execution of C<op>. C<user_data> will be passed to the callback as the last
argument.
