Destination for Trace Messages

You can send trace messages to various destinations depending on the type of your

application. By default, on Unix the messages are sent to stderr using fprintf() and if
|
|
we are on Windows and have a windows applications then register a HTTraceCallback
|
|
function. This is done with HTTrace_setCallback. It tells HTTrace to call a
|
|
HTTraceCallback. If your compiler has problems with va_list, then you may forget about
|
|
registering the callback and instead macro HTTrace as follows: #define HTTrace

MyAppSpecificTrace
