No. C or the std C library does not provide such facilities.
When malloc()/realloc()/calloc() returns an error (NULL), it means
there is not space left to allocate, you could free() some
unused previously allocated buffers, do something else that does
not need to allocate memory or exit();
If you reach that level, it's maybe time for you to rethink,
your design and thight things up.
