IOCTL_STORAGE_CHECK_VERIFY

The IOCTL_STORAGE_CHECK_VERIFY DeviceIoControl operation determines whether a device's media is accessible; for example, whether the media is in the device.

dwIoControlCode = IOCTL_STORAGE_CHECK_VERIFY ; // operation code

lpInBuffer = NULL; // address of input buffer; not used; must be NULL

nInBufferSize = 0; // size of input buffer; not used; must be zero

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 an input buffer. Not used with this operation. Set to NULL.

nInBufferSize

Specifies the size, in bytes, of the buffer pointed to by lpInBuffer. Not used with this operation. Set to zero.

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 and the device media is accessible, DeviceIoControl returns TRUE.

If the operation fails, DeviceIoControl returns FALSE.
