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. */
