ADCMD_FINISH

abort writes in progress to audio channels

ADCMD_FINISH is a command for multiple audio channels. For each selected channel (io_Unit), if the allocation key (ioa_AllocKey) is correct and there is a write (CMD_WRITE)in progress, ADCMD_FINISH aborts the current write immediately or at the end of the current cycle depending on the sync flag (ADIOF_SYNCCYCLE). If the allocation key is incorrect ADCMD_FINISH returns an error (ADIOERR_NOALLOCATION). ADCMD_FINISH is synchronous and only replies (mn_ReplyPort) if the quick flag (IOF_QUICK) is clear. Do not use ADCMD_FINISH in interrupt code at interrupt level 5 or higher.

io_Device

Pointer to device node, must be set by (or copied from I/O block set by) OpenDevice function

io_Unit

Bit map of channels to finish (bits 0 thru 3 correspond to channels 0 thru 3)

io_Command

Command number for ADCMD_FINISH

io_Flags

Flags, must be cleared if not used: IOF_QUICK - (CLEAR) reply I/O request ADIOF_SYNCCYCLE- (CLEAR) finish immediately

(SET) finish at the end of current

cycle

ioa_AllocKey

Allocation key, must be set by (or copied from I/O block set by) OpenDevice function or ADCMD_ALLOCATE command

io_Unit

Bit map of channels successfully finished (bits 0 thru 3 correspond to channels 0 thru 3)

io_Error

Error number: 0 - no error ADIOERR_NOALLOCATION - allocation key (ioa_AllocKey)

does not match key for channel
