-==Syntax== +===== Syntax =====
- DosQCurDisk (DriveNumber, LogicalDriveMap)+
  
-==Parameters== 
-;DriveNumber (PUSHORT) - output : Address of the number of the default drive, for example: 
- '''Value  Definition''' 
- 1      A 
- 2      B 
- .      . 
-;LogicalDriveMap (PULONG) - output : Address of the bit map (stored in the low-order portion of the 32-bit, doubleword area) where the system returns the mapping of the logical drives. Logical Drives A to Z have a one-to-one mapping with the bit positions 0 to 25 of the map; for example, bit 0 is drive A, bit 1 is drive B, and so forth. The settings of these bits indicate which drives exist: 
- '''Value  Definition''' 
- 0       The logical drive does not exist. 
- 1       The logical drive exists.
