8.4 Disabling Tracing Using gc_StopTrace( )
The gc_StopTrace( ) function stops the logging of debug information for a specific line device that
was started using gc_StartTrace( ).
To use this feature, the line device must be the handle for a trunk or virtual board. After the
gc_StopTrace( ) function returns success, the application may be notified of the availability of the
last remaining trace data via GCEV_TRACEDATA.
Sample application code
Note: The following sample code was written for an application running on a system in which an Intel
NetStructure DMT160TEC board was used as the network interface, an Intel NetStructure
DMV2400A board was used as a play/record resource board, and the boards were connected via a
CT Bus.
