AcPlPlotErrorHandlerLock

AcPlPlotErrorHandlerLock.h

The AcPlPlotErrorHandlerLock class facilitates locking of the application error handler inserted into the plot configuration manager's error handler chain. The design allows only one application-provided error handler to be inserted in the chain a time. The lock class provides a mechanism for ensuring that applications do not step on each other's error handlers. It also removes error handlers from the chain when the lock is destroyed or released.
