NAME¶
POSIX::AtFork - Hook registrations at
fork(2)
SYNOPSIS¶
# POSIX interface:
use POSIX::AtFork qw(:all);
pthread_atfork(\&prepare, \&parent, \&child);
# or per-hook interfaces:
POSIX::AtFork->add_to_prepare(\&prepare);
POSIX::AtFork->add_to_parent(\&parent);
POSIX::AtFork->add_to_child(\&child);
# registered callbacks can be removed
POSIX::AtFork->delete_from_prepare(\&prepare);
POSIX::AtFork->delete_from_parent( \&parent);
POSIX::AtFork->delete_from_child( \&child);
DESCRIPTION¶
This module is an interface to
pthread_atfork(3), which registeres handlers
called before and after
fork(2).
INTERFACE¶
pthread_atfork(\&prepare, \&parent, \&child)¶
Registeres hooks called before "fork()" (
&prepare) and
after (
&parent for the parent,
&child for the child).
All callbacks are called with the current opname, namely "fork",
"system", "backtick", and etc.
This exportable function is an interface to
pthread_atfork(3).
POSIX::AtFork->add_to_prepare(\&hook)¶
The same as "pthread_atfork(\&hook, undef, undef)".
POSIX::AtFork->add_to_parent(\&hook)¶
The same as "pthread_atfork(undef, \&hook, undef)".
POSIX::Atfork->add_to_child(\&hook)¶
The same as "pthread_atfork(undef, undef, \&hook)".
POSIX::AtFork->delete_from_prepare(\&hook)¶
Deletes
&hook from the "prepare" hook list.
POSIX::AtFork->delete_from_parent(\&hook)¶
Deletes
&hook from the "parent" hook list.
POSIX::AtFork->delete_from_child(\&hook)¶
Deletes
&hook from the "child" hook list.
