Byte Array Objects
******************

PyByteArrayObject

   This subtype of "PyObject" represents a Python bytearray object.

PyTypeObject PyByteArray_Type

   This instance of "PyTypeObject" represents the Python bytearray
   type; it is the same object as "bytearray" in the Python layer.


Type check macros
=================

int PyByteArray_Check(PyObject *o)

   Return true if the object *o* is a bytearray object or an instance
   of a subtype of the bytearray type.

int PyByteArray_CheckExact(PyObject *o)

   Return true if the object *o* is a bytearray object, but not an
   instance of a subtype of the bytearray type.


Direct API functions
====================

PyObject* PyByteArray_FromObject(PyObject *o)

   Return a new bytearray object from any object, *o*, that implements
   the *buffer protocol*.

PyObject* PyByteArray_FromStringAndSize(const char *string, Py_ssize_t len)

   Create a new bytearray object from *string* and its length, *len*.
   On failure, *NULL* is returned.

PyObject* PyByteArray_Concat(PyObject *a, PyObject *b)

   Concat bytearrays *a* and *b* and return a new bytearray with the
   result.

Py_ssize_t PyByteArray_Size(PyObject *bytearray)

   Return the size of *bytearray* after checking for a *NULL* pointer.

char* PyByteArray_AsString(PyObject *bytearray)

   Return the contents of *bytearray* as a char array after checking
   for a *NULL* pointer.

int PyByteArray_Resize(PyObject *bytearray, Py_ssize_t len)

   Resize the internal buffer of *bytearray* to *len*.


Macros
======

These macros trade safety for speed and they don't check pointers.

char* PyByteArray_AS_STRING(PyObject *bytearray)

   Macro version of "PyByteArray_AsString()".

Py_ssize_t PyByteArray_GET_SIZE(PyObject *bytearray)

   Macro version of "PyByteArray_Size()".
