.. highlightlang:: c .. _bytearrayobjects: Byte Array Objects ------------------ .. index:: object: bytearray .. versionadded:: 2.6 .. c:type:: PyByteArrayObject This subtype of :c:type:`PyObject` represents a Python bytearray object. .. c:var:: PyTypeObject PyByteArray_Type This instance of :c:type:`PyTypeObject` represents the Python bytearray type; it is the same object as ``bytearray`` in the Python layer. Type check macros ^^^^^^^^^^^^^^^^^ .. c:function:: 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. .. c:function:: 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 ^^^^^^^^^^^^^^^^^^^^ .. c:function:: PyObject* PyByteArray_FromObject(PyObject *o) Return a new bytearray object from any object, *o*, that implements the buffer protocol. .. XXX expand about the buffer protocol, at least somewhere .. c:function:: 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. .. c:function:: PyObject* PyByteArray_Concat(PyObject *a, PyObject *b) Concat bytearrays *a* and *b* and return a new bytearray with the result. .. c:function:: Py_ssize_t PyByteArray_Size(PyObject *bytearray) Return the size of *bytearray* after checking for a *NULL* pointer. .. c:function:: char* PyByteArray_AsString(PyObject *bytearray) Return the contents of *bytearray* as a char array after checking for a *NULL* pointer. .. c:function:: 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. .. c:function:: char* PyByteArray_AS_STRING(PyObject *bytearray) Macro version of :c:func:`PyByteArray_AsString`. .. c:function:: Py_ssize_t PyByteArray_GET_SIZE(PyObject *bytearray) Macro version of :c:func:`PyByteArray_Size`.
