| REVISION HISTORY |
| |
| Description: Put declaration of getfill in this file. |
| |
| Description: Remove prstflag from get_ics_info declaration. |
| |
| Description: Trivial change of the data type of one of the parameters to |
| get_ics_info. |
| |
| Description: Change where get_ics_info is declared. |
| |
| Description: Clean up comments |
| |
| Description: (1) Add declaration of binary tree search function for Huffman |
| decoding |
| (2) #if the traditional and optimized linear seach methods. |
| |
| Description: Modified per review comments |
| (1) delete #if traditional and optimized linear seach methods |
| |
| Description: Merged Ken's change on getics: delete pFrameInfo from argument |
| list |
| |
| Description: Added function definition for table specific huffman decoding |
| functions. |
