I'm currently reading Silberschatz's Operating Systems chapter on virtual memory.
Here it is stated that :
" With vfork(), the parent process is suspended, and the child process uses the address space of the parent. Because vfork() does not use copy-on-write, if the child process changes any pages of the parent’s address space, the altered pages will be visible to the parent once it resumes.
[...] Vfork() is intended to be used when the child process calls exec() immediately after creation. "
If I recall correctly, exec( ) will replace the current process image.
So dose calling vfork() with a subsequent exec() call replace the parent's process image as well since the address space is shared?
