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 return 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 display the error messages on a graphics mode screen without abort‐ ing the program. You can call this function even when Allegro has not been initialised. 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. */
