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