IOCTL_STORAGE_EJECT_MEDIA

The IOCTL_STORAGE_EJECT_MEDIA DeviceIoControl operation causes media to be ejected from a SCSI device.

dwIoControlCode = IOCTL_STORAGE_EJECT_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 TRUE.

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

Remarks

IOCTL_STORAGE_EJECT_MEDIA may or may not be supported on SCSI devices that support removable media.
