 Name:         »buffoper« - Set or read record/playback mode

 Opcode:       136

 Syntax:       int32_t buffoper( int16_t mode );

 Description:  The XBIOS routine buffoper sets or reads the record and 
               playback mode of the harware sound system.

               If the value -1 is passed for mode, then the current 
               setting will be established. Otherwise mode is coded as 
               follows:

                Bit  Operation 
                 0   DMA sound playback 
                 1   Loop playback of sound currently playing 
                 2   DMA sound recording 
                 1   Loop recording within the currently set record 
                     buffer (as set by Buffptr) 

               Set bits switch an operation on, cleared bits off.

 Return value: If successfull the function returns the value 0. If -1 
               was passed for mode, the return will show the current 
               state of the sound system, whose coding corresponds to 
               the parameter mode.

 Availability: The function is only available on computers of the 
               Falcon series, or with extended XBIOS routines (_SND).

 Group:        Sound routines
