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.
