Question

I am trying to complete a college assignment, and the marking criteria specifies 5% for memory management – specifically for having no memory leaks.

As I understand it, memory leaks in simple C programs, are only caused by pointers which have become abandoned by the program – ie, malloc/calloc/etc calls which are never have a corresponding free.

My question is in 3 parts:

1. Whats the simplest way on Solaris
   and OSX to ‘prove’ that you haven’t
   leaked any memory?
2. Does XCode have
   any tools to help determine memory
   leaks?
3. Does the operating system
   release all previously allocated
   memory within a c program once the
   process ends?

Valgrind is your friend.
