Functions of the DLL
The communication between the DLL and LandMark Mobile relies
on named event signaling and named shared memory. All pulled
data based events have time-outs, but the pushed data event blocks
the third party application until LandMark Mobile signals with
new data. The DLL is aware of LandMark Mobile unloading and
releases the block so that the third party application is not blocked
if LandMark Mobile is no longer running.
