/** 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, ...
|
||||||
|
|
||||||
|
Note that audio data do not have exact block addressing. If you read a
|
||||||
|
sequence of successive blocks then you will get a seamless stream
|
||||||
|
of data. But the actual start and end position of this audio stream
|
||||||
|
will differ by a few dozens of milliseconds, depending on individual
|
||||||
|
CD and individual drive.
|
||||||
|
Expect leading and trailing zeros, as well as slight truncation.
|
||||||
|
|
||||||
|
@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)
|
||||||
|
It may be slightly below 0, depending on drive and
|
||||||
|
medium. -150 is a lower limit.
|
||||||
|
@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.)
