◆ __has_feature

#define __has_feature ( x ) 0

Definition at line 9 of file BLI_asan.h.

◆ ASAN_POISON_MEMORY_REGION

#define ASAN_POISON_MEMORY_REGION	(		addr,
			size ) (void)(0 && ((size) != 0 && (addr) != NULL))

◆ ASAN_UNPOISON_MEMORY_REGION

#define ASAN_UNPOISON_MEMORY_REGION	(		addr,
			size ) (void)(0 && ((size) != 0 && (addr) != NULL))

◆ BLI_asan_poison

#define BLI_asan_poison	(		addr,
			size ) ASAN_POISON_MEMORY_REGION(addr, size)

Mark a region of memory as "freed". When using address sanitizer, accessing the given memory region will cause an use-after-poison error. This can be used to find errors when dealing with uninitialized memory in custom containers.

◆ BLI_asan_unpoison

#define BLI_asan_unpoison	(		addr,
			size ) ASAN_UNPOISON_MEMORY_REGION(addr, size)

Mark a region of memory as usable again.
