- Type stringobject represents a character 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 string objects, to test
- an object for string-ness, and to get the
- 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 nil objects.
