The Trace property is used to enable or disable the tracing
of network function calls and is primarily used as a debugging tool.
When enabled, each function call is logged to a file, including the
function parameters, return value and error code if applicable. This
facility can be enabled and disabled at run time, and the trace log
file can be specified by setting the TraceFile property. All
function calls that are being logged are appended to the trace file,
if it exists. If no trace file exists when tracing is enabled, the
trace file is created.
The tracing facility is enabled or disabled for an entire process.
This means that once tracing is enabled for a given instance of the
object, all of the function calls made by the process will be
If tracing is not enabled, there is no negative impact on
performance or throughput. Once enabled, application performance can
degrade, especially in those situations in which multiple processes
are being traced or the trace file is fairly large. Since trace files
can grow very quickly, even with modest applications, it is
recommended that you delete the file when it is no longer needed.
