/** Read CD audio sectors in random access mode.
The drive must be grabbed successfully before calling this function.
Only CD audio tracks with 2352 bytes per sector can be read this way.
I.e. not data tracks, not CD-video-stream, ...
@param d The drive from which to read.
It must be a real MMC drive (i.e. not a stdio file)
and it must have a CD loaded (i.e. not DVD or BD).
@param sector_no The sector number (Logical Block Address)
@param data A memory buffer capable of taking data_size bytes
@param data_size The amount of data to be read. This must be aligned
to full multiples of 2352.
@param data_count The amount of data actually read (interesting on error)
@param flag Bitfield for control purposes:
bit0= - reserved -
bit1= do not submit error message if read error
bit2= on error do not try to read a second time
with single block steps.
bit3= Enable DAP : "flaw obscuring mechanisms like
audio data mute and interpolate"
bit4= return -3 on SCSI error
5 64 00 ILLEGAL MODE FOR THIS TRACK
and prevent this error from being reported as
event message. Do not retry reading in this case.
(Useful to try the last two blocks of a CD
track which might be non-audio because of TAO.)
@return 1=sucessful , <=0 an error occured
with bit3: -2= permission denied error
@since 1.2.6
