What happens to the malloc'ed memory when exit(1) is encountered?
c, exit, free, malloc, memory-leaks
Solution
Once you call `exit`, OS takes all the allocated memory back. So no need to call `free`.
Edit: But It's generally good practice to free memory you allocated in your program as you may overlook it the call to free when you modify it in the future.
Problem
In C, if I allocate a memory using `malloc` and during the execution, the program encounters an exception/error and exits with a manually incorporated `exit(1)` statement in the program, does C compiler automatically frees the memory before making the unexpected exit or do I have to manually do this just before the `exit(1)` line in the program. I use the gcc-4.5.2 compiler on Ubuntu 32bit platform.
