NAME

       Devel::PPPort - Perl/Pollution/Portability


SYNOPSIS

           Devel::PPPort::WriteFile();   # defaults to ./ppport.h
           Devel::PPPort::WriteFile('someheader.h');

           # Same as above but retrieve contents rather than write file
           my $contents = Devel::PPPort::GetFileContents();
           my $contents = Devel::PPPort::GetFileContents('someheader.h');


DESCRIPTION

       Perl's API has changed over time, gaining new features, new functions,
       increasing its flexibility, and reducing the impact on the C namespace
       environment (reduced pollution). The header file written by this
       module, typically ppport.h, attempts to bring some of the newer Perl
       API features to older versions of Perl, so that you can worry less
       about keeping track of old releases, but users can still reap the
       benefit.

       "Devel::PPPort" contains two functions, "WriteFile" and
       "GetFileContents".  "WriteFile"'s only purpose is to write the ppport.h
       C header file.  This file contains a series of macros and, if
       explicitly requested, functions that allow XS modules to be built using
       older versions of Perl. Currently, Perl versions from 5.003 to 5.20 are
       supported.

       "GetFileContents" can be used to retrieve the file contents rather than
       writing it out.

       This module is used by "h2xs" to write the file ppport.h.

   Why use ppport.h?
       You should use ppport.h in modern code so that your code will work with
       the widest range of Perl interpreters possible, without significant
       additional work.

       You should attempt older code to fully use ppport.h, because the
       reduced pollution of newer Perl versions is an important thing. It's so
       important that the old polluting ways of original Perl modules will not
       be supported very far into the future, and your module will almost
       certainly break! By adapting to it now, you'll gain compatibility and a
       sense of having done the electronic ecology some good.

   How to use ppport.h
       Don't direct the users of your module to download "Devel::PPPort".
       They are most probably no XS writers. Also, don't make ppport.h
       optional. Rather, just take the most recent copy of ppport.h that you
       can find (e.g. by generating it with the latest "Devel::PPPort" release
       from CPAN), copy it into your project, adjust your project to use it,
       and distribute the header along with your module.

   Running ppport.h
       But ppport.h is more than just a C header. It's also a Perl script that
       can check your source code. It will suggest hints and portability
       notes, and can even make suggestions on how to change your code. You
       can run it like any other Perl program:

           perl ppport.h [options] [files]

       It also has embedded documentation, so you can use

           perldoc ppport.h

       to find out more about how to use it.


FUNCTIONS

   WriteFile
       "WriteFile" takes one optional argument. When called with one argument,
       it expects to be passed a filename. When called with no arguments, it
       defaults to the filename ppport.h.

       The function returns a true value if the file was written successfully.
       Otherwise it returns a false value.

   GetFileContents
       "GetFileContents" behaves like "WriteFile" above, but returns the
       contents of the would-be file rather than writing it out.


COMPATIBILITY

       ppport.h supports Perl versions from 5.003 to 5.20 in threaded and non-
       threaded configurations.

   Provided Perl compatibility API
       The header file written by this module, typically ppport.h, provides
       access to the following elements of the Perl API that is not available
       in older Perl releases:

   Perl API not supported by ppport.h
       There is still a big part of the API not supported by ppport.h.  Either
       because it doesn't make sense to back-port that part of the API, or
       simply because it hasn't been implemented yet. Patches welcome!

       Here's a list of the currently unsupported API, and also the version of
       Perl below which it is unsupported:
