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
