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");
