VERSION

This document describes XS::MRO::Compat version 0.14.

SYNOPSIS

        # In your XS distribution

        use inc::Module::Install;

        # Add the following to your Makefile.PL
        use_ppport;
        requires_xs 'XS::MRO::Compat'; # see Module::Install::XSUtil

        /* Then put the "include" directive in your Module.xs */

        /* ... */
        #include "ppport.h"

        #include "mro_compat.h"

        /* Now you can use several mro functions in your Module.xs:
                mro_get_linear_isa()
                mro_get_pkg_gen()
                mro_method_changed_in()
        */

        # And use XS::MRO::Compat in your module
        use XS::MRO::Compat;

DESCRIPTION

XS::MRO::Compat provides several mro functions for XS modules.

This feature is provided by Module::Install::XSUtil.

XS interface

AV* mro_get_linear_isa(HV* stash)

The same as mro::get_linear_isa() in Perl.

In 5.10 or later, it is just a public Perl API.

In 5.8.x, it calls mro::get_linear_isa provided by MRO::Compat. It has a cache mechanism as Perl 5.10 does, so it is much faster than the direct call of mro::get_linear_isa provided by MRO::Compat.

void mro_method_changed_in(HV* stash)

The same as mro::method_changed_in() in Perl.

U32 mro_get_pkg_gen(HV* stash)

The same as mro::get_pkg_gen() in Perl. This is not a Perl API.

This may evaluate stash more than once.

DEPENDENCIES

Perl 5.8.1 or later, and a C compiler.
