register_trace_handler(3) Allegro manual register_trace_handler(3) NAME register_trace_handler - Registers a custom handler for trace output. Alle- gro 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 re- turn 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 func- tion 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"); SEE ALSO al_trace(3), TRACE(3), register_assert_handler(3) Allegro version 4.4.3 register_trace_handler(3)
