/** This header file includes all the definitions for the
|
||
|
|
** base pygame extensions. This header only requires
|
||
|
|
** SDL and Python includes. The reason for functions
|
||
|
|
** prototyped with #define's is to allow for maximum
|
||
|
|
** python portability. It also uses python as the
|
||
|
|
** runtime linker, which allows for late binding. For more
|
||
|
|
** information on this style of development, read the Python
|
||
|
|
** docs on this subject.
|
||
|
|
** http://www.python.org/doc/current/ext/using-cobjects.html
|
||
|
|
**
|
||
|
|
** If using this to build your own derived extensions,
|
||
|
|
** you'll see that the functions available here are mainly
|
||
|
|
** used to help convert between python objects and SDL objects.
|
||
|
|
** Since this library doesn't add a lot of functionality to
|
||
|
|
** the SDL libarary, it doesn't need to offer a lot either.
|
||
|
|
**
|
||
|
|
** When initializing your extension module, you must manually
|
||
|
|
** import the modules you want to use. (this is the part about
|
||
|
|
** using python as the runtime linker). Each module has its
|
||
|
|
** own import_xxx() routine. You need to perform this import
|
||
|
|
** after you have initialized your own module, and before
|
||
|
|
** you call any routines from that module. Since every module
|
||
|
|
** in pygame does this, there are plenty of examples.
|
||
|
|
**
|
||
|
|
** The base module does include some useful conversion routines
|
||
|
|
** that you are free to use in your own extension.
|
||
|
|
**
|
||
|
|
** When making changes, it is very important to keep the
|
||
|
|
** FIRSTSLOT and NUMSLOT constants up to date for each
|
||
|
|
** section. Also be sure not to overlap any of the slots.
|
||
|
|
** When you do make a mistake with this, it will result
|
||
|
|
** is a dereferenced NULL pointer that is easier to diagnose
|
||
|
|
** than it could be :]
