.. cfunction:: wchar_t* PyUnicode_AsWideCharString(PyUnicodeObject *unicode, Py_ssize_t *size)
Convert the Unicode object to a wide character string. The output string
always ends with a nul character. If *size* is not *NULL*, write the number
of wide characters (including the nul character) into *\*size*.
Returns a buffer allocated by :cfunc:`PyMem_Alloc` (use :cfunc:`PyMem_Free`
to free it) on success. On error, returns *NULL*, *\*size* is undefined and
raises a :exc:`MemoryError`.
