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.
