register_assert_handler(3) Allegro manual register_assert_handler(3) NAME register_assert_handler - Registers a custom handler for assert failures. Allegro game programming library. SYNOPSIS #include <allegro.h> void register_assert_handler(int (*handler)(const char *msg)); DESCRIPTION Supplies a custom handler function for dealing with assert failures. Your callback will be passed a formatted error message in ASCII, and should re- turn non-zero if it has processed the error, or zero to continue with the default actions. You could use this to ignore assert failures, or to dis- play the error messages on a graphics mode screen without aborting the pro- gram. You can call this function even when Allegro has not been ini- tialised. Example: int show_but_continue(const char *text) { alert("Uh oh...", "Fasten your seat belts.", text, "&Go on!", NULL, 'g', 0); return 1; } ... register_assert(show_but_continue); ASSERT(0); /* This won't crash the program now. */ SEE ALSO al_assert(3), ASSERT(3), register_trace_handler(3) Allegro version 4.4.3 register_assert_handler(3)
