DosPhysicalDisk Parameter - pParams

pParams (PVOID) - input

The address of the buffer used for input parameters.

The input parameters required for each function are as follows (all lengths are in bytes):

┌──────────┬─────────────┬─────────────────────────────────────┐
│Function  │ParmLen      │Input Parameters                     │
├──────────┼─────────────┼─────────────────────────────────────┤
│ 1        │ 0           │None - must be set to zero.          │
├──────────┼─────────────┼─────────────────────────────────────┤
│ 2        │string length│ASCIIZ string that specifies the     │
│          │             │partitionable disk.                  │
├──────────┼─────────────┼─────────────────────────────────────┤
│ 3        │ 2           │Handle obtained from Function 2.     │
└──────────┴─────────────┴─────────────────────────────────────┘

The ASCIIZ string used to specify the partitionable disk must be of the following format:

number : <null byte>

Where:

number

specifies the partitionable disk number (1-based) in ASCII.
colon ( : )
must be present.
<null byte>
is the byte of zero for the ASCIIZ string.
