Byte Array Objects — Python v3.0 documentation

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.
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.
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.
Py_ssize_t PyByteArray_Size(PyObject *bytearray)¶
Return the size of bytearray after checking for a NULL pointer.
Py_ssize_t PyByteArray_GET_SIZE(PyObject *bytearray)¶
Macro version of PyByteArray_Size that doesn’t do pointer checking.
char* PyByteArray_AsString(PyObject *bytearray)¶
Return the contents of bytearray as a char array after checking for a NULL pointer.
char* PyByteArray_AS_STRING(PyObject *bytearray)¶
Macro version of PyByteArray_AsString that doesn’t check pointers.
PyObject* PyByteArray_Concat(PyObject *a, PyObject *b)¶
Concat bytearrays a and b and return a new bytearray with the result.
PyObject* PyByteArray_Resize(PyObject *bytearray, Py_ssize_t len)¶
Resize the internal buffer of bytearray to len.
