Hi,

Please explain the Nice Value and File Mode creation mask in the context of fork () system call. Also tell me What is FILE MODE CREATION MASK?

Thanks.

I am a bit confused and mixing the concepts that "In Indirect Communication, two processes can only communicate if they mail box." Sharing a mail box is like sharing memory.

Thanks.
