MemoryView objects - Python 3.5.9 documentation 编辑
A memoryview
object exposes the C level buffer interface as a Python object which can then be passed around like any other object.
- PyObject *
PyMemoryView_FromObject
(PyObject *obj) 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.
- PyObject *
PyMemoryView_FromMemory
(char *mem, Py_ssize_t size, int flags) Create a memoryview object using mem as the underlying buffer. flags can be one of
PyBUF_READ
orPyBUF_WRITE
.New in version 3.3.
- PyObject *
PyMemoryView_FromBuffer
(Py_buffer *view) Create a memoryview object wrapping the given buffer structure view. For simple byte buffers,
PyMemoryView_FromMemory()
is the preferred function.
- PyObject *
PyMemoryView_GetContiguous
(PyObject *obj, int buffertype, char order) 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.
- int
PyMemoryView_Check
(PyObject *obj) Return true if the object obj is a memoryview object. It is not currently allowed to create subclasses of
memoryview
.
