shm_open() - opens a new shared memory object.

ftruncate() -  will set the size of the shared memory.  In our program set it to 4096 via the SIZE constant.

mmap() - map fiels into memory

shm_unlink() - gets rid of the shared memory object


--------------------------------------------------------------
To compile on Linux systems, enter

	gcc -lrt -o producer producer.c

	gcc -lrt -o consumer consumer.c


-o -> specifies the output file name
-l -> specifies link with shared libraries
rt -> rt , real time extension library

--------------------------------------------------------------

First run the producer which generates the sequence in shared memory:

	./producer  (ex. ./producer 35)

Followed by running the consumer which outputs the sequence:

	./consumer
