I've no idea how you'd do a generic solution that'd work on anything, but..

I had to do something like this a while back but since my app was being
called from a batch file, I could 'cheat' and make use of the 'chdir'
command. If you type 'chdir X:' (where X is the drive you're interested in)
at a DOS prompt, it'll return the current directory for that drive,
according to that DOS session. 

My function did a simple system call something like:
 system(sprintf("chdir %s > %s", {drive_letter, temp_filename}), 2)
I'd then read the single line in that file and use that instead of, in my
case, 'M:' or 'N:'.

I used that simple trick to deal with a whole bunch of files in a batch
process on Win2000 and I could avoid messing with the current
drive/directory, which would have broken the 'main' batch file.
