register_trace_handler3alleg

Usage

Overview

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");
