There are two source files: child.c and parent.c. I create a shared memory in parent.c, and I can
read these data in child.c. I need to output data when I read the character "a". How to create a
unnamed semaphore to constantly read data from a shared memory. Should I create a semaphore
in two source files or only the child.c?
Thank you in advance!
