// Bytes object interface

#ifndef Py_BYTESOBJECT_H

#define Py_BYTESOBJECT_H

#ifdef __cplusplus

extern "C" {

#endif

Type PyBytesObject represents a byte string. An extra zero byte is

reserved at the end to ensure it is zero-terminated, but a size is

present so strings with null bytes in them can be represented. This

is an immutable object type.

There are functions to create new bytes objects, to test

an object for bytes-ness, and to get the

byte string value. The latter function returns a null pointer

if the object is not of the proper type.

There is a variant that takes an explicit size as well as a

variant that assumes a zero-terminated string. Note that none of the

functions should be applied to NULL pointer.
