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 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 aborting 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. */
