/* Type PyByteArrayObject represents a mutable array of bytes.
|
|
* The Python API is that of a sequence;
|
|
* the bytes are mapped to ints in [0, 256).
|
|
* Bytes are not characters; they may be used to encode characters.
|
|
* The only way to go between bytes and str/unicode is via encoding
|
|
* and decoding.
|
|
* For the convenience of C programmers, the bytes type is considered
|
|
* to contain a char pointer, not an unsigned char pointer.
