| REVISION HISTORY |
| |
| Description: Changed file name to bitreorder_tab.c and .h. Also, updated the |
| module description. |
| |
| Description: Define "const Word16 *reorderBits[NUM_MODES-1]" as |
| "const Word16 *const reorderBits[NUM_MODES-1]". |
| |
| Description: Added #ifdef __cplusplus and removed "extern" from table |
| definition. Removed corresponding header file from Include |
| section. |
| |
| Description: Put "extern" back. |
