Registers a custom handler for trace output.


void register_trace_handler(int (*handler)(const char *msg));
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. Example:
   int network_broadcaster(const char *text)
      int f;

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

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