Will you please give me some example of the case which I should > not share the resources ? Thanking you all in advance. It's not a question of "I should not share the resources" - fork() and friends don't let you choose what to share or not share. It's a matter of being *aware* of what is or is not shared. 'man 2 fork' gives an extensive list of what the child does and does not inherit. Note that in some places it says "inherits" - this usually refers to settings, and means "you get a copy of the same value". In places where it says "inherits copies", that means you got another reference to the same object (mostly in regards to file system objects). The clone() syscall is useful if you wish to control what you do or don't inherit from your parent. It's also a very good way to shoot yourself in the foot, as the semantics are subtly different from fork().
