MemoryView objects

A memoryview object exposes the C level buffer interface <bufferobjects> as a Python object which can then be passed around like any other object.

This instance of PyTypeObject represents the Python memoryview type. This is the same object as memoryview in the Python layer.

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.

Flag to request a readonly buffer.

Flag to request a writable buffer.

Create a memoryview object using mem as the underlying buffer. flags can be one of PyBUF_READ or PyBUF_WRITE.

3.3

Create a memoryview object wrapping the given buffer structure view. For simple byte buffers, PyMemoryView_FromMemory is the preferred function.

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.

buffertype can be one of PyBUF_READ or PyBUF_WRITE.

Return true if the object obj is a memoryview object. It is not currently allowed to create subclasses of memoryview. This function always succeeds.

Return a pointer to the memoryview's private copy of the exporter's buffer. mview must be a memoryview instance; this macro doesn't check its type, you must do it yourself or you will risk crashes.

Return either a pointer to the exporting object that the memoryview is based on or NULL if the memoryview has been created by one of the functions PyMemoryView_FromMemory or PyMemoryView_FromBuffer. mview must be a memoryview instance.
