Byte Array Objects

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().
