ppport.h  view on Meta::CPAN 

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 *

Although the purpose of F<ppport.h> is to keep you from having to concern
yourself with what version you are running under, there may arise instances
where you have to do so.  These macros, the same ones as in base Perl, are
available to you in all versions, and are what you should use:

ppport.h  view on Meta::CPAN 


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.
