Process forking (copy-on-write)
Implements the fork system call which creates a child process as a copy
of the current process. Provides both full-copy (fork_process) and
copy-on-write (cow_fork) variants. COW fork marks all user-space
pages as read-only in both parent and child, deferring physical copies
to the page fault handler when either process writes.
Functions§
- cow_
fork - Fork with copy-on-write semantics.
- fork_
process - Fork current process
