ASSERT(3)                       Allegro manual                       ASSERT(3)


ASSERT - Debugging helper macro to assert. Allegro game programming library.


#include <allegro.h> void ASSERT(condition);


Debugging helper macro. Normally compiles away to nothing, but if you defined the preprocessor symbol DEBUGMODE before including Allegro headers, it will check the supplied condition and call al_assert() if it fails, whose default action is to stop the program and report the assert. You can use this macro even when Allegro has not been initialised. Example: #define DEBUGMODE #include ... void my_blitter(BITMAP *source, int flags) { int some_variables; ASSERT(source != NULL); ASSERT(flags & GAME_RUNNING); ... }
