PyBuffer_IsContiguous clj

(PyBuffer_IsContiguous view order)

Return 1 if the memory defined by the view is C-style (order is 'C') or Fortran-style (order is 'F') contiguous or either one (order is 'A'). Return 0 otherwise. This function always succeeds.

PyBuffer_Release clj

(PyBuffer_Release view)

Release the buffer view and decrement the reference count for view->obj. This function MUST be called when the buffer is no longer being used, otherwise reference leaks may occur.

It is an error to call this function on a buffer that was not obtained via PyObject_GetBuffer().

PyBuffer_ToContiguous clj

(PyBuffer_ToContiguous buf src len order)

Copy len bytes from src to its contiguous representation in buf. order can be 'C' or 'F' (for C-style or Fortran-style ordering). 0 is returned on success, -1 on error.

This function fails if len != src->len.

PyObject_CheckBuffer clj

(PyObject_CheckBuffer obj)

Return 1 if obj supports the buffer interface otherwise 0. When 1 is returned, it doesn’t guarantee that PyObject_GetBuffer() will succeed. This function always succeeds.

PyObject_GetBuffer clj

(PyObject_GetBuffer exporter view flags)

Send a request to exporter to fill in view as specified by flags. If the exporter cannot provide a buffer of the exact type, it MUST raise PyExc_BufferError, set view->obj to NULL and return -1.

On success, fill in view, set view->obj to a new reference to exporter and return 0. In the case of chained buffer providers that redirect requests to a single object, view->obj MAY refer to this object instead of exporter (See Buffer Object Structures).

Successful calls to PyObject_GetBuffer() must be paired with calls to PyBuffer_Release(), similar to malloc() and free(). Thus, after the consumer is done with the buffer, PyBuffer_Release() must be called exactly once.
