Module Name:

    htdebug.c


Abstract:

    This module contains the debug functions


Author:
    23-Apr-1992 Thu 20:01:55 updated  -by-  Daniel Chou (danielc)
        changed 'CHAR' type to 'BYTE' type, this will make sure if compiled
        under MIPS the default 'unsigned char' will not affect the signed
        operation on the single 8 bits


    28-Mar-1992 Sat 20:53:29 updated  -by-  Daniel Chou (danielc)
        Modify sprintf for by not using va_start
