Creating more than one shared memory by a process
I am not sure whether more than one shared memory can be created by a process
I tried creating three shared memory by a process.
I am using shmget system call to create the shared memory.
The flag parameter what I am using is IPC_CREATE | 0666 for all the three.
I had also tried with IPC_CREATE | 0644
I am getting three different ids for shmget and three different pointers for shmat().But some junk value is coming in the shared memory created.
I doubt that the shared memory created is overlapping.Whether the flag parameter has to be changed.
Please clear my doubt
Your problem is probably buried in the details. How about posting the code that demonstrates the problem?
