-/* --- C API ----------------------------------------------------*/\r
-\r
-/* Short explanation of what this C API export mechanism does\r
- and how it works:\r
-\r
- The _ssl module needs access to the type object defined in\r
- the _socket module. Since cross-DLL linking introduces a lot of\r
- problems on many platforms, the "trick" is to wrap the\r
- C API of a module in a struct which then gets exported to\r
- other modules via a PyCapsule.\r
-\r
- The code in socketmodule.c defines this struct (which currently\r
- only contains the type object reference, but could very\r
- well also include other C APIs needed by other modules)\r
- and exports it as PyCapsule via the module dictionary\r
- under the name "CAPI".\r
-\r
- Other modules can now include the socketmodule.h file\r
- which defines the needed C APIs to import and set up\r
- a static copy of this struct in the importing module.\r
-\r
- After initialization, the importing module can then\r
- access the C APIs from the _socket module by simply\r
- referring to the static struct, e.g.\r
-\r
- Load _socket module and its C API; this sets up the global\r
- PySocketModule:\r
-\r
- if (PySocketModule_ImportModuleAndAPI())\r
- return;\r
-\r
-\r
- Now use the C API as if it were defined in the using\r
- module:\r
-\r
- if (!PyArg_ParseTuple(args, "O!|zz:ssl",\r
-\r
- PySocketModule.Sock_Type,\r
-\r
- (PyObject*)&Sock,\r
- &key_file, &cert_file))\r
- return NULL;\r
-\r
- Support could easily be extended to export more C APIs/symbols\r
- this way. Currently, only the type object is exported,\r
- other candidates would be socket constructors and socket\r
- access functions.\r
