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);
             ...
          }
