Subject: [PATCH] clone.2, fork.2: Document ERESTARTNOINTR error code

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|

|
||||
Since Linux 2.6.17, clone and fork syscalls return ERESTARTNOINTR
|
||||
when interrupted by a signal before newly created process is added
|
||||
to its process group.
|
||||
This error code can only be seen by ptrace at syscall exit tracing.
|
||||
|
||||
The information was obtained from kernel source code:
