IOCTL_DISK_VERIFY
The IOCTL_DISK_VERIFY
DeviceIoControl
operation performs a logical format of a specified extent on a disk.
dwIoControlCode = IOCTL_DISK_VERIFY; // operation code
lpInBuffer;
// address of input buffer
nInBufferSize;
// size of input buffer
lpOutBuffer = NULL;
// address of output buffer; not used; must be NULL
nOutBufferSize = 0;
// size of output buffer; not used; must be zero
lpBytesReturned;
// address of actual bytes of output
Parameters
lpInBuffer
Points to a
buffer that contains a VERIFY_INFORMATION data structure.
nInBufferSize
Specifies the
size, in bytes, of the buffer pointed to by lpInBuffer, which must be
large enough to contain a VERIFY_INFORMATION data structure.
lpOutBuffer
Points to an
output buffer. Not used with this operation. Set to NULL.
nOutBufferSize
Specifies the
size, in bytes, of the buffer pointed to by lpOutBuffer. Not used with
this operation. Set to zero.
lpBytesReturned
Points to a DWORD
that receives the actual size, in bytes, of the data stored into lpOutBuffer.
Return Values
If the
operation succeeds, DeviceIoControl returns TRUE.
If the
operation fails, DeviceIoControl returns FALSE. To get extended error
information, call GetLastError.
Remarks
This device
I/O control operation is for disk devices. Floppy disk drivers, however, need not
handle this operation.
