Use conditions according to the platforms

TraceStart is used to save the requested information in a file. By default, this file is created in the UNIX temporary directory and is named "Trace_<Project>.txt".

TraceStart is used to display the requested information in the current page or to store it in a file.

In AWP mode, TraceStart can only be used to save the requested information in a file.

Closing the trace window

TraceEnd is used to close the trace window.

If the trFile constant is specified, TraceEnd stops saving to the trace file.

Trace window

The trace window displayed from a browser code differs from the trace window displayed from a server code. Therefore, two different trace windows can be opened at the same time.
