Re: how to release memory?

I also have a few doubts with regard to releasing memory and other
resources. When an error occurs at some point in the program then
usually we proceed by printing an error message and propogating a flag
backwards ( return (1) ) indicating error. Is it a good policy to
release all the resources which were held up till then (when the error
occured) in the program. For eg. a file may be open which must be
closed, a data structure that must be freed etc. It can vary at
different points in the program, different resources may have to be
freed depending on what was allocated till that point. At the very end
(just before main process ends) all the resources can be freed.
