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.
If you know that your XS module uses features only available in
newer Perl releases, if you're aware that it uses C++ comments,
and if you want all suggestions as a single patch file, you could
use something like this:
perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff
If you only want your code to be scanned without any suggestions
for changes, use:
perl ppport.h --nochanges
You can specify a different C<diff> program or options, using
the C<--diff> option:
perl ppport.h --diff='diff -C 10'
This would output context diffs with 10 lines of context.
If you want to create patched copies of your files instead, use:
perl ppport.h --copy=.new
To display portability information for the C<newSVpvn> function,
use:
perl ppport.h --api-info=newSVpvn
Since the argument to C<--api-info> can be a regular expression,
you can use
perl ppport.h --api-info=/_nomg$/
to display portability information for all C<_nomg> functions or
perl ppport.h --api-info=/./
to display information for all known API elements.
=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
send a bug report to L<perlbug@perl.org|mailto:perlbug@perl.org>.
