al_assert(3)			Allegro manual			  al_assert(3)

NAME
       al_assert - Asserts at the specified file and line number. Allegro game
       programming library.

SYNOPSIS
       #include <allegro.h>

       void al_assert(const char *file, int line);

DESCRIPTION
       Raises an assert for an error at the specified file  and	 line  number.
       The  file  parameter  is always given in ASCII format. By default, this
       will call the system driver's assert handler. If	 there	is  none,  the
       error  will  be	sent to stderr and the program will abort. However, if
       the environment variable ALLEGRO_ASSERT is set, this function writes  a
       message into the file specified by the environment variable and program
       execution will continue. If none of this behaviours is wanted, you  can
       override them with a custom assert handler.

       You will usually want to use the ASSERT() macro instead of calling this
       function directly.
