Start.
Got semaphore Resource id #%i.
Success aquire semaphore Resource id #%i.
Success to attach shared memory : %i.
Write var1 to shared memory.
Write var2 to shared memory.
Read var1=Variable 1.
Read var2=Variable 2.
Semaphore Resource id #%i released.
Shared memory successfully removed from SysV.
semaphore removed successfully from SysV.
