picklebuffer

Pickle buffer objects

A pickle.PickleBuffer object wraps a buffer-providing object <bufferobjects> for out-of-band data transfer with the pickle module.

This instance of PyTypeObject represents the Python pickle buffer type. This is the same object as pickle.PickleBuffer in the Python layer.

Return true if op is a pickle buffer instance. This function always succeeds.

Create a pickle buffer from the object obj.

This function will fail if obj doesn't support the buffer protocol <bufferobjects>.

On success, return a new pickle buffer instance. On failure, set an exception and return NULL.

Analogous to calling pickle.PickleBuffer with obj in Python.

Get a pointer to the underlying Py_buffer that the pickle buffer wraps.

The returned pointer is valid as long as picklebuf is alive and has not been released. The caller must not modify or free the returned Py_buffer. If the pickle buffer has been released, raise ValueError.

On success, return a pointer to the buffer view. On failure, set an exception and return NULL.

Release the underlying buffer held by the pickle buffer.

Return 0 on success. On failure, set an exception and return -1.

Analogous to calling pickle.PickleBuffer.release in Python.
