IOCTL_STORAGE_CHECK_VERIFY info  Overview  Group

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 a nonzero value.

If the operation fails, DeviceIoControl returns zero.
