IRAPISession::CeUnmountDBVol (Windows Embedded CE 6.0)
This method unmounts a database volume on a remote Windows Embedded CE–based device.
All cached data is flushed to permanent storage when this method is called. A single database volume can be mounted more than once by different applications. Each time the volume is mounted a reference count is incremented. A mounted database volume does not unmount until all applications that mounted the volume call IRAPISession::CeUnmountDBVol.
