TTYPrint is a generic way for libwww to send error and logging messages to the user interface or a
logging file. Several option exist to define the TTYPrint target. These are defined in HTUtils.h.
You may define the WWWTRACE_MODE to
- WWWTRACE_FILE to fprintf output to a file..
 
- WWWTRACE_STDERR to fprintf output to stderr.
 
- WWWTRACE_TTY to call a TTYPrint function defined in 
your application.
WWWTRACE_FILE
All calls to the macro TTYPrint will result in an fprintf to HT_TRACE_FILE (also defined in HTUtils.h ). This defaults to "WWWTRACE.TXT".
WWWTRACE_STDERR
By default, the unix and WIN32 console builds send all the output
to stderr.
WWWTRACE_TTY
The windowed builds cannot use stderr or file redirection to a
console, so they send messages to an application defined function called TTYPrint. This function
must be of type TTYPrint_t.  If the build involves dynamic
linking, the calls are made through a function pointer called PTTYPrint. The application must
set this pointer to point to a function of type TTYPrint_t, eg.
	*PTTYPrint = &AppTTYPrint;
