ASTMM_LIBC

#define ASTMM_LIBC   ASTMM_IGNORE

Definition at line 31 of file astmm.c.

DEBUG_CHAOS_RETURN

#define DEBUG_CHAOS_RETURN	(		c,
			f
	)

DEBUG_CHAOS returns failure randomly.

DEBUG_CHAOS_RETURN(failure); can be used to fake failure of functions such as memory allocation, for the purposes of testing failure handling.
