register_trace_handler - Man Page

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


#include <allegro.h>

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. 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. */
      TRACE("Networked tracing activated\n");
