drive label to device name

[jotd]

Hi,

I'm a bit lazy but I'd like to get the device name (ex: CD0 for a given path:
(ex: Games:mygame)

(i.e. convert Games: to CD0

thanks

One possible solution (Not necessarily the best but quite simple):

lock = Lock("<your path>",SHARED_LOCK), get lock->fl_Task (struct FileLock), then scan DosList for entry with dol_type==DLT_DEVICE with matching dol_task. dol_Name points to device name.

just out of interest, why do you actually want to do this?

just to check if the path is located in CD0: drive, because only CD0: drive is readable with the RN CD32 load routine.

Use this:

file_lock = Lock("Games:mygame",SHARED_LOCK);
cd_lock = Lock("CD0:",SHARED_LOCK);
result = SameLock(file_lock,cd_lock);

if result is LOCK_SAME_VOLUME, then the game directory is on the CD.
