I read an article (http://www.linuxjournal.com/article/4681
), talking about memory issue. It refers to one function, named `malloc_usable_space()' which can report the usage of a memory. However, whilst checking the man page or looking up on the internet, I can not find any usage or synopsis on this function. Some pages simply refer to the name of this function only.
My problem is how to use to function? What is it usage?
Thank you very much.
