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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
