File.ejectMountableWithOperation

void ejectMountableWithOperation(gio.types.MountUnmountFlags flags,  gio.mount_operation.MountOperation mountOperation =  null,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

Starts an asynchronous eject on a mountable. When this operation has completed, callback will be called with user_user data, and the operation can be finalized with gio.file.File.ejectMountableWithOperationFinish.

If cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.types.IOErrorEnum.Cancelled will be returned.

Parameters

`flags`	flags affecting the operation
`mountOperation`	a #GMountOperation, or null to avoid user interaction
`cancellable`	optional #GCancellable object, null to ignore
`callback`	a #GAsyncReadyCallback to call when the request is satisfied
