Test for presence of mapped drive

[cprettyman]

Is there a way, in Lisp, to test for the presence of a mapped drive? I currently have a few things that test for the presence of a particular file, but I want to just check to see that a given drive letter is responding, without being concerned with what's in it. IE, I want to set up something that says
if the O drive is there, do A, else do B

Thanks

Hi CP,

If you have DOSLib, you can use the DOS_DRIVEP function.

For example:

Command: (dos_drivep "C:")
T
Command: (dos_drivep "Z:")
nil

DOSLib is free from www.mcneel.com.

Unfortunately, this one won't work since there's no filename given, it'll
always return nil.
