=head1 DESCRIPTION
In order for a Perl extension (XS) module to be as portable as possible
across differing versions of Perl itself, certain steps need to be taken.
=over 4
=item *
Including this header is the first major one. This alone will give you
access to a large part of the Perl API that hasn't been available in
earlier Perl releases. Use
perl ppport.h --list-provided
to see which API elements are provided by ppport.h.
=item *
You should avoid using deprecated parts of the API. For example, using
global Perl variables without the C<PL_> prefix is deprecated. Also,
some API functions used to have a C<perl_> prefix. Using this form is
also deprecated. You can safely use the supported API, as F<ppport.h>
will provide wrappers for older Perl versions.
=item *
If you use one of a few functions or variables that were not present in
earlier versions of Perl, and that can't be provided using a macro, you
have to explicitly request support for these functions by adding one or
more C<#define>s in your source code before the inclusion of F<ppport.h>.
These functions or variables will be marked C<explicit> in the list shown
by C<--list-provided>.
Depending on whether you module has a single or multiple files that
use such functions or variables, you want either C<static> or global
variants.
For a C<static> function or variable (used only in a single source
file), use:
#define NEED_function
#define NEED_variable
For a global function or variable (used in multiple source files),
use:
#define NEED_function_GLOBAL
#define NEED_variable_GLOBAL
Note that you mustn't have more than one global request for the
same function or variable in your project.

To avoid namespace conflicts, you can change the namespace of the
explicitly exported functions / variables using the C<DPPP_NAMESPACE>
macro. Just C<#define> the macro before including C<ppport.h>:
#define DPPP_NAMESPACE MyOwnNamespace_
#include "ppport.h"
The default namespace is C<DPPP_>.
=back
The good thing is that most of the above can be checked by running
F<ppport.h> on your source code. See the next section for
details.
=head1 EXAMPLES
To verify whether F<ppport.h> is needed for your module, whether you
should make any changes to your code, and whether any special defines
should be used, F<ppport.h> can be run as a Perl script to check your
source code. Simply say:
perl ppport.h
The result will usually be a list of patches suggesting changes
that should at least be acceptable, if not necessarily the most
efficient solution, or a fix for all possible problems.
=head1 BUGS
If this version of F<ppport.h> is causing failure during
the compilation of this module, please check if newer versions
of either this module or C<Devel::PPPort> are available on CPAN
before sending a bug report.
If F<ppport.h> was generated using the latest version of
C<Devel::PPPort> and is causing failure of this module, please
file a bug report here: L<https://github.com/mhx/Devel-PPPort/issues/>
Please include the following information:
=over 4
=item 1.
The complete output from running "perl -V"
=item 2.
This file.
=item 3.
The name and version of the module you were trying to build.
=item 4.
A full log of the build that failed.
=item 5.
Any other information that you think could be relevant.
=back
For the latest version of this code, please get the C<Devel::PPPort>
module from CPAN.
