- * Purpose: The implementation of LIST data structure.
- *
- * Author: Kyle Hsu
- *
- * Date: Sep 4, 2002
- *
- * Functions:
- * s_dwGetUINT32 - Convert from unsigned char [] to unsigned long in a portable way
- * s_vPutUINT32 - Convert from unsigned long to unsigned char [] in a portable way
- * s_vClear - Reset the state to the empty message.
- * s_vSetKey - Set the key.
- * MIC_vInit - Set the key.
- * s_vAppendByte - Append the byte to our word-sized buffer.
- * MIC_vAppend - call s_vAppendByte.
- * MIC_vGetMIC - Append the minimum padding and call s_vAppendByte.
