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.
mn_ReplyPort- pointer to message port that receives I/O request
if the quick flag (IOF_QUICK) is clear
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
