*
*  Mnemonic: SIcbreg
*  Abstract: This routine will register a callback in the table. Callbacks
*            are "unregistered" by passing a null function pointer.
*  Parms:    gptr - pointer to the general information block (SIHANDLE)
*            type - Type of callback to register (SI_CB_xxxxx)
*            fptr - Pointer to the function to register
*            dptr - Pointer that the user wants the callback function to get
*  Returns:  Nothing.
*  Date:     23 January 1995
