POSIX::AtFork(3) 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.
