ASSERT(3)			Allegro	manual			     ASSERT(3)

NAME
       ASSERT -	Debugging helper macro to assert. Allegro game programming li-
       brary.

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 ini-
       tialised. Example:

	  #define DEBUGMODE
	  #include
	  ...
	  void my_blitter(BITMAP *source, int flags)
	  {
	     int some_variables;
	     ASSERT(source != NULL);
	     ASSERT(flags & GAME_RUNNING);
	     ...
	  }
