--EXPECT--
Start.
Got semaphore.
Success acquire semaphore.
Success to attach shared memory.
Write var1 to shared memory.
Write var2 to shared memory.
Read var1=Variable 1.
Read var2=Variable 2.
Semaphore released.
Shared memory successfully removed from SysV.
semaphore removed successfully from SysV.
End.
