Re: fork system call

["SK malik" <srikrishanmalik@xxxxxxxxx>]

fork creates a new process which initially shares everything with the parent(excluding the task struct), as soon as on of the processes tries to write to any shared page it(the page) is duplicated and separate copies are given to each process.

Hello,
I am sorry for asking silly question.

       In windows basic execution unit is thread, and Linux does not differentiate between thread and process( I mean Linux doesn't give special treatment for thread essentially they are normal process except they share some resource with other process).   If I use fork to create process, does it create thread that run in the same thread group as parent run or does it create another standalone process?

Fork system call is equivalent to clone(SIGCHLD,0, so I think fork create new standalone process.

Please clarify.
