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. */ /* Caching the hash (ob_shash) saves recalculation of a string's hash value.
