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);
             ...
          }
