NAME

       register_trace_handler  -  Registers a custom handler for trace output.
       Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void register_trace_handler(int (*handler)(const char *msg));

DESCRIPTION

       Supplies a custom handler function for dealing with trace output.  Your
       callback  will be passed a formatted error message in ASCII, and should
       return non-zero if it has processed the message, or  zero  to  continue
       with the default actions. You could use this to ignore trace output, or
       to display the messages on a second monochrome monitor,  etc.  You  can
       call this function even when Allegro has not been initialised. Example:

          int network_broadcaster(const char *text)
          {
             int f;

             for (int f = 0; f
                send_msg_to_client(client[f], text);

             return 0; /* Let normal tracing occur. */
          }
          ...
             register_trace_handler(network_broadcaster);
             TRACE("Networked tracing activated\n");
