IOCTL_STORAGE_LOAD_MEDIA info  Overview  Group

The IOCTL_STORAGE_LOAD_MEDIA DeviceIoControl operation causes media to be loaded into a device.

dwIoControlCode = IOCTL_STORAGE_LOAD_MEDIA;   // 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, DeviceIoControl returns a nonzero value.

If the operation fails, DeviceIoControl returns a nonzero value. To get extended error information, call GetLastError.

Remarks

The IOCTL_STORAGE_LOAD_MEDIA is valid only for devices that support loadable media.
