NAME

pike_string - internal pike shared strings

DESCRIPTION

This is the internal type for representing pike strings. They have ref counts and they are shared though a global hash table. The C type is a struct pike_string that has two public members: str and len. str is an array of char which contain the actual string. It is guaranteed that the string is null terminated, but the string can also contain zeroes before the end. len is of course the length of the string. Since strings are shared you may _never_ modify the contents of a string, except for adding/subtracting references when approperiate. The only exception to this is when creating a new shared string with begin_shared_string which has not yet been linked to the hash table with end_shared_string.
