Process typical storage space

How environment variables and command-line arguments are passed to the process

5 Forms of normal termination of a process and 3 forms of abnormal termination

How to dynamically allocate additional storage space to a process

SETJMP and LONGJMP functions and their interaction with the stack, and the state effect on the Auto register volatile static global 5 types of variables

Can a pointer be volatile?

What happens to the parameters of the function that are volatile?

The Getrlimit and Setrlimit functions read and set the soft and hard limits.
