Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

The DSK_REDETERMINEMEDIA function redetermines the media on a block device
and updates the volume in the drive. This function is normally issued after
the volume identification information has been changed (for example, by
formatting the disk). This function should be called only if the volume is
locked.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
pbCommand  Points to the variable that contains a reserved value. The value
           must be zero.
 
hDevice    Identifies the disk drive that receives the device-control
           function. The handle must have been created previously by using
           the DosOpen function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
