Devel::PPPort - Perl/Pollution/Portability
Devel::PPPort::WriteFile(); # defaults to ./ppport.h Devel::PPPort::WriteFile('someheader.h');
"Devel::PPPort" contains a single function, called "WriteFile". Its 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 5.9.3 are supported.
This module is used by "h2xs" to write the file ppport.h.
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.
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.
The function returns a true value if the file was written successfully. Otherwise it returns a false value.
