diff Python/getargs.c @ 12570:3dbe41380266 legacy-trunk
Brian Hooper <brian_takashi@hotmail.com>:
Added 'u' and 'u#' tags for PyArg_ParseTuple - these turn a
PyUnicodeObject argument into a Py_UNICODE * buffer, or a Py_UNICODE *
buffer plus a length with the '#'. Also added an analog to 'U'
for Py_BuildValue.
