IOCTL_STORAGE_MEDIA_REMOVAL info  Overview  Group

The IOCTL_STORAGE_MEDIA_REMOVAL DeviceIoControl operation enables or disables the mechanism that ejects media, for those devices possessing that locking capability.

dwIoControlCode = IOCTL_STORAGE_MEDIA_REMOVAL;   // operation code 

lpInBuffer;         // address of input buffer 

nInBufferSize;      // size of input buffer 

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 a buffer that contains a PREVENT_MEDIA_REMOVAL data structure.

A TRUE value for that structure’s PreventMediaRemoval member specifies that media removal is prevented (the device is locked). A FALSE value specifies that media removal is allowed.

nInBufferSize
Specifies the size, in bytes, of the buffer pointed to by lpInBuffer, which must be large enough to contain a PREVENT_MEDIA_REMOVAL data structure.
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_MEDIA_REMOVAL operation is valid only for devices that support removable media.
