IOCTL_DISK_FORMAT_TRACKS info  Overview  Group

The IOCTL_DISK_FORMAT_TRACKS DeviceIoControl operation formats a specified, contiguous set of tracks on a disk.

dwIoControlCode = IOCTL_DISK_FORMAT_TRACKS;   // 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 FORMAT_PARAMETERS data structure.

nInBufferSize

Specifies the size, in bytes, of the buffer pointed to by lpInBuffer, which must be large enough to contain a FORMAT_PARAMETERS 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 a nonzero value.

If the operation fails, DeviceIoControl returns zero. To get extended error information, call GetLastError.

Remarks

This device I/O control operation is for floppy disk devices only.
