| D | unshare.rst | 1 unshare system call
4 This document describes the new system call, unshare(). The document
42 unshare() system call adds a primitive to the Linux thread model that
43 allows threads to selectively 'unshare' any resources that were being
44 shared at the time of their creation. unshare() was conceptualized by
46 of the discussion on POSIX threads on Linux. unshare() augments the
48 shared resources without creating a new process. unshare() is a natural
55 unshare() would be useful to large application frameworks such as PAM
58 when creating a new process using fork or clone, unshare() can benefit
61 where unshare() can be used.
