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);
             ...
          }
