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 value: New reference.

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

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

Return value: New reference.

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

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

Return value: New reference.

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. The returned array always has an extra null byte appended.
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().
