ASSERT(3alleg4)                  Allegro manual                  ASSERT(3alleg4)



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);
             ...
          }
