💖 POSIX::AtFork 💖

okay bestie, listen. the manual page is POSIX::AtFork(3pm) (user contributed perl documentation, if you're keeping score) and it is literally the little module that hooks you up at fork(2). fork hook registrations!! we love a before-and-after situation. 🎀

✨ NAME ✨

POSIX::AtFork — hook registrations at fork(2). that's it, that's the whole name, and it ate. 👑

🌸 SYNOPSIS 🌸

here's the vibe, copied exactly, no cap:

# 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);

yes you can register, yes you can delete, yes we're doing both. main character energy fr fr. 💅

🦋 DESCRIPTION 🦋

so like. this module is an interface to pthread_atfork(3), and what that does is register handlers that get called before and after fork(2). that's the whole point. before. after. slay. 🌈

💜 INTERFACE 💜

pthread_atfork(\&prepare, \&parent, \&child)

registers hooks called before fork() (that's &prepare) and after — &parent for the parent, &child for the child. three slots, one function, iconic behavior.

all callbacks are called with the current opname, namely "fork", "system", "backtick", and etc. so yes, they know what you did. 🫶

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. bye bestie 👋

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.
