NAME

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

SYNOPSIS

#include <allegro.h>

void ASSERT(condition);

DESCRIPTION

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);
       ...
    }
