This call determines the current default drive for the requesting process.

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.

Return Code

rc (USHORT) - return Return code description is: * 0 NO_ERROR
