/** Retrieve some media information which is mainly specific to CD. For other
media only the bits in reply parameter valid are supposed to be meaningful.
@param drive The drive to query.
@param disc_type A string saying either "CD-DA or CD-ROM", or "CD-I",
or ""CD-ROM XA", or "undefined".
@param disc_id A 32 bit number read from the media. (Meaning unclear yet)
@param bar_code 8 hex digits from a barcode on media read by the drive
(if the drive has a bar code reader built in).
@param app_code The Host Application Code which must be set in the Write
Parameters Page if the media is not unrestricted (URU==0).
@param valid Replies bits which indicate the validity of other reply
parameters or the state of certain CD info bits:
bit0= disc_type is valid
bit1= disc_id is valid
bit2= bar_code is valid
bit3= disc_app_code is valid
bit4= Disc is unrestricted (URU bit, 51h READ DISC INFO)
This seems to be broken with my drives. The bit is
0 and the validity bit for disc_app_code is 0 too.
bit31= Disc is nominally erasable (Erasable bit)
This will be set with overwriteable media which
libburn normally considers to be unerasable blank.
