What is the correct way to handle “out of memory”?

Question

Recently, I work on a video player program on Windows for a CCTV program. As the program has to decode and play many videos streams at the same time, I think it might meet

Answer 1

It depends on the type of application that you are working on. If the application does work that is divided into discrete tasks where an individual task can be allowed to fail, then checking memory allocations can be recovered from gracefully.

But in many cases, the only reasonable way to respond to a malloc failure is by terminating the program. Allowing your code to just crash on the inevitable null dereference will achieve that. It would certainly always be better to dump a log entry or error message explaining the error, but in the real world we work on limited schedules. Sometimes the return on investment of pedantic error handling isn't there.
