Hi - I am working on a patch where I have an argument that can either be a
unicode string or binary data, I parse the argument using the
PyArg_ParseTuple method using the s* format specification and get a
Py_Buffer.
I now need to convert this Py_Buffer object to a Py_Unicode and pass it into
a function. What is the best way to do this? If I determine that the passed
argument was binary using another flag parameter then I am passing
Py_Buffer->buf as a pointer to the start of the data.
This is in winsound module, here's the relevant code snippet
sound_playsound(PyObject *s, PyObject *args)
{
Py_buffer *buffer;
int flags;
int ok;
LPCWSTR pszSound;
if (PyArg_ParseTuple(args, "s*i:PlaySound", &buffer, &flags)) {
if (flags & SND_ASYNC && flags & SND_MEMORY) {
/* Sidestep reference counting headache; unfortunately this also
prevent SND_LOOP from memory. */
PyBuffer_Release(buffer);
PyErr_SetString(PyExc_RuntimeError, "Cannot play asynchronously
from memory");
return NULL;
}
if(flags & SND_MEMORY) {
pszSound = buffer->buf;
}
else {
/* pszSound = ????; */
}
