Byte Array Objects ****************** New in version 2.6. 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()".
