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