-/* This file is the C file that corresponds to the Ada package spec
- Stringt. It was created manually from stringt.ads and stringt.adb
-
- Note: only the access functions are provided, since the tree transformer
- is not allowed to modify the tree or its auxiliary structures.
-
- This package contains routines for handling the strings table which is
- used to store string constants encountered in the source, and also those
- additional string constants generated by compile time concatenation and
- other similar processing.
-
- A string constant in this table consists of a series of Char_Code values,
- so that 16-bit character codes can be properly handled if this feature is
- implemented in the scanner.
-
- There is no guarantee that hashing is used in the implementation. This
- means that the caller cannot count on having the same Id value for two
- identical strings stored separately.
-
- The String_Id values reference entries in the Strings table, which
- contains String_Entry records that record the length of each stored string
- and its starting location in the String_Chars table. */
