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 :] **/ #if defined(HAVE_SNPRINTF) /* defined in python.h (pyerrors.h) and SDL.h \ (SDL_config.h) */ #undef HAVE_SNPRINTF /* remove GCC redefine warning */ #endif // This must be before all else #if defined(__SYMBIAN32__) && defined(OPENC) #include <sys/types.h> #if defined(__WINS__) void * _alloca(size_t size); #define alloca _alloca #endif #endif #define PG_STRINGIZE_HELPER(x) #x #define PG_STRINGIZE(x) PG_STRINGIZE_HELPER(x) #define PG_WARN(desc) message(__FILE__ "(" PG_STRINGIZE(__LINE__) "): WARNING: " #desc) /* This is unconditionally defined in Python.h */ #if defined(_POSIX_C_SOURCE) #undef _POSIX_C_SOURCE #endif #include <Python.h> /* the version macros are defined since version 1.9.5 */ #define PG_MAJOR_VERSION 1 #define PG_MINOR_VERSION 9 #define PG_PATCH_VERSION 6 #define PG_VERSIONNUM(MAJOR, MINOR, PATCH) (1000*(MAJOR) + 100*(MINOR) + (PATCH)) #define PG_VERSION_ATLEAST(MAJOR, MINOR, PATCH) \ (PG_VERSIONNUM(PG_MAJOR_VERSION, PG_MINOR_VERSION, PG_PATCH_VERSION) >= \ PG_VERSIONNUM(MAJOR, MINOR, PATCH)) /* Cobjects vanish in Python 3.2; so we will code as though we use capsules */ #if defined(Py_CAPSULE_H) #define PG_HAVE_CAPSULE 1 #else #define PG_HAVE_CAPSULE 0 #endif #if defined(Py_COBJECT_H) #define PG_HAVE_COBJECT 1 #else #define PG_HAVE_COBJECT 0 #endif #if !PG_HAVE_CAPSULE #define PyCapsule_New(ptr, n, dfn) PyCObject_FromVoidPtr(ptr, dfn) #define PyCapsule_GetPointer(obj, n) PyCObject_AsVoidPtr(obj) #define PyCapsule_CheckExact(obj) PyCObject_Check(obj) #endif /* Pygame uses Py_buffer (PEP 3118) to exchange array information internally; * define here as needed. */ #if !defined(PyBUF_SIMPLE) typedef struct bufferinfo { void *buf; PyObject *obj; Py_ssize_t len; Py_ssize_t itemsize; int readonly; int ndim; char *format; Py_ssize_t *shape; Py_ssize_t *strides; Py_ssize_t *suboffsets; void *internal; } Py_buffer; /* Flags for getting buffers */ #define PyBUF_SIMPLE 0 #define PyBUF_WRITABLE 0x0001 /* we used to include an E, backwards compatible alias */ #define PyBUF_WRITEABLE PyBUF_WRITABLE #define PyBUF_FORMAT 0x0004 #define PyBUF_ND 0x0008 #define PyBUF_STRIDES (0x0010 | PyBUF_ND) #define PyBUF_C_CONTIGUOUS (0x0020 | PyBUF_STRIDES) #define PyBUF_F_CONTIGUOUS (0x0040 | PyBUF_STRIDES) #define PyBUF_ANY_CONTIGUOUS (0x0080 | PyBUF_STRIDES) #define PyBUF_INDIRECT (0x0100 | PyBUF_STRIDES) #define PyBUF_CONTIG (PyBUF_ND | PyBUF_WRITABLE) #define PyBUF_CONTIG_RO (PyBUF_ND) #define PyBUF_STRIDED (PyBUF_STRIDES | PyBUF_WRITABLE) #define PyBUF_STRIDED_RO (PyBUF_STRIDES) #define PyBUF_RECORDS (PyBUF_STRIDES | PyBUF_WRITABLE | PyBUF_FORMAT) #define PyBUF_RECORDS_RO (PyBUF_STRIDES | PyBUF_FORMAT) #define PyBUF_FULL (PyBUF_INDIRECT | PyBUF_WRITABLE | PyBUF_FORMAT) #define PyBUF_FULL_RO (PyBUF_INDIRECT | PyBUF_FORMAT) #define PyBUF_READ 0x100 #define PyBUF_WRITE 0x200 #define PyBUF_SHADOW 0x400 typedef int (*getbufferproc)(PyObject *, Py_buffer *, int); typedef void (*releasebufferproc)(Py_buffer *); #endif /* #if !defined(PyBUF_SIMPLE) */ /* Flag indicating a pg_buffer; used for assertions within callbacks */ #ifndef NDEBUG #define PyBUF_PYGAME 0x4000 #endif #define PyBUF_HAS_FLAG(f, F) (((f) & (F)) == (F)) /* Array information exchange struct C type; inherits from Py_buffer * * Pygame uses its own Py_buffer derived C struct as an internal representation * of an imported array buffer.
