| // Provides functionality for mapping between |
| // LCID and Posix IDs. |
| // |
| // Note: All classes and code in this file are |
| // intended for internal use only. |
| // |
| // Methods of interest: |
| // void initializeMapRegions(); |
| // unsigned long convertToLCID(const int8_t*); |
| // const int8_t* convertToPosix(unsigned long); |
| // |
| // Kathleen Wilson, 4/30/96 |
| // |
| // Date Name Description |
| // 3/11/97 aliu Fixed off-by-one bug in assignment operator. Added |
| // setId() method and safety check against |
| // MAX_ID_LENGTH. |
| // 04/23/99 stephen Added C wrapper for convertToPosix. |

| * This code is used only internally by putil.c/uprv_getDefaultLocaleID(). |
| * This means that this could be much simpler code, and the mapping |
| * from Win32 locale ID numbers to POSIX locale strings should |
