shared memory

Simple example of inter process communication with shm_open().

The main process forks itself and then prints whatever the child writes into te shared memory. The child writes 5 time "hallo <#>" and then exits. After printing 5 times whatever the child wrote, the main process unlinks the shared memory object.

Note

The file noerror.c does the same as main.c, but no error handling.

If you kill the process before exiting, you need to close the shared memory object manually.

rm -f /dev/shm/SHARED_MEM

compile

make

run

./main
