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);


      ...


   }
