register_assert_handler(3) Allegro manual register_assert_handler(3)NAMEregister_assert_handler - Registers a custom handler for assert fail‐
ures. 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 con‐
tinue 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. */
