rc = DosQueryCurrentDisk( pulDrive, pulLogical );
Parameters
- PULONG pulDrive (output)
- Pointer to the current drive number. (1=A, 2=B etc.)
- PULONG pulLogical (output)
- Pointer to a 32-bit bit area where each of the 26 lowest bits represents a drive (0=A, 1=B etc.) If bit n is set(=1) then the drive corresponding to n exists.
Returns
- APIRET rc
- 0 NO_ERROR
