The AR System C API programs consist of the four basic sections:
Startup/initialization - Call ARInitialization to perform server and network-specific initialization operations for connecting to the AR System server.
System work - Call one or more C API functions to perform the specific work of your program.
Free allocated memory - Call one or more of the FreeAR functions (or use the free function) to free all allocated memory associated with a specific data structure. For more information, see Freeing-allocated-memory.
Shutdown/cleanup - Call ARTermination to perform environment-specific cleanup routines and disconnect from the AR System server. If you use floating licenses and do not disconnect from the server, your license token becomes unavailable for other users for the defined time-out interval.
