A memoryview
object exposes the C level buffer interface as a Python object which can then be passed around like
any other object.
PyMemoryView_FromObject
(PyObject *obj)Return value: New reference.
Create a memoryview object from an object that provides the buffer interface. If obj supports writable buffer exports, the memoryview object will be read/write, otherwise it may be either read-only or read/write at the discretion of the exporter.
PyMemoryView_FromMemory
(char *mem, Py_ssize_t size, int flags)Return value: New reference.
Create a memoryview object using mem as the underlying buffer.
flags can be one of PyBUF_READ
or PyBUF_WRITE
.
New in version 3.3.
PyMemoryView_FromBuffer
(Py_buffer *view)Return value: New reference.
Create a memoryview object wrapping the given buffer structure view.
For simple byte buffers, PyMemoryView_FromMemory()
is the preferred
function.
PyMemoryView_GetContiguous
(PyObject *obj, int buffertype, char order)Return value: New reference.
Create a memoryview object to a contiguous chunk of memory (in either ‘C’ or ‘F’ortran order) from an object that defines the buffer interface. If memory is contiguous, the memoryview object points to the original memory. Otherwise, a copy is made and the memoryview points to a new bytes object.
PyMemoryView_Check
(PyObject *obj)memoryview
.PyMemoryView_GET_BUFFER
(PyObject *mview)PyMemoryView_GET_BASE
(PyObject *mview)NULL
if the memoryview has been created by one of the functions PyMemoryView_FromMemory()
or PyMemoryView_FromBuffer()
. mview must be a memoryview instance.
