/*
|

|
|
Type PyBytesObject represents a byte string. An extra zero byte is
|
||
|
|
reserved at the end to ensure it is zero-terminated, but a size is
|
||
|
|
present so strings with null bytes in them can be represented. This
|
||
|
|
is an immutable object type.
|
||
|
|
|
||
|
|
There are functions to create new bytes objects, to test
|
||
|
|
an object for bytes-ness, and to get the
|
||
|
|
byte string value. The latter function returns a null pointer
|
||
|
|
if the object is not of the proper type.
|
||
|
|
There is a variant that takes an explicit size as well as a
|
||
|
|
variant that assumes a zero-terminated string. Note that none of the
|
||
|
|
functions should be applied to NULL pointer.
