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. 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");
