+ | 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: | ||
