pszDevice (PSZ) - input

Pseudocharacter or spool device name.

A drive designation or a pseudocharacter device name when flag is 0 or 1. A drive designation is an ASCIIZ string consisting of the drive name followed by a colon. If an attachment is successful, all requests to that drive are routed to the specified file-system driver. If a detachment is successful, the drive is removed from the system's name space.

pszDevice points to the name of a spooled device when flag is 2 or 3. The pszDevice format is the same as above. Requests to that name are not seen by the file-system driver.

A pseudocharacter device name (single file device) is an ASCIIZ string consisting of the file-name subdirectory \DEV\. All requests to that name are routed to the specified file-system driver after a successful attachment. A successful detachment removes the name from the system's name space.
