.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is an interface to \f(CWpthread_atfork(3)\fR, which registeres
handlers called before and after \f(CWfork(2)\fR.
.SH "INTERFACE"
.IX Header "INTERFACE"
.SS "pthread_atfork(\e&prepare, \e&parent, \e&child)"
.IX Subsection "pthread_atfork(&prepare, &parent, &child)"
Registeres hooks called before \f(CW\*(C`fork()\*(C'\fR (\fI&prepare\fR) and after
(\fI&parent\fR for the parent, \fI&child\fR for the child).
.PP
All callbacks are called with the current opname, namely \f(CW\*(C`fork\*(C'\fR,
\&\f(CW\*(C`system\*(C'\fR, \f(CW\*(C`backtick\*(C'\fR, and etc.
.PP
This exportable function is an interface to \f(CWpthread_atfork(3)\fR.
.SS "POSIX::AtFork\->add_to_prepare(\e&hook)"
.IX Subsection "POSIX::AtFork->add_to_prepare(&hook)"
The same as \f(CW\*(C`pthread_atfork(\e&hook, undef, undef)\*(C'\fR.
.SS "POSIX::AtFork\->add_to_parent(\e&hook)"
.IX Subsection "POSIX::AtFork->add_to_parent(&hook)"
The same as \f(CW\*(C`pthread_atfork(undef, \e&hook, undef)\*(C'\fR.
.SS "POSIX::Atfork\->add_to_child(\e&hook)"
.IX Subsection "POSIX::Atfork->add_to_child(&hook)"
The same as \f(CW\*(C`pthread_atfork(undef, undef, \e&hook)\*(C'\fR.
.SS "POSIX::AtFork\->delete_from_prepare(\e&hook)"
.IX Subsection "POSIX::AtFork->delete_from_prepare(&hook)"
Deletes \fI&hook\fR from the \f(CW\*(C`prepare\*(C'\fR hook list.
.SS "POSIX::AtFork\->delete_from_parent(\e&hook)"
.IX Subsection "POSIX::AtFork->delete_from_parent(&hook)"
Deletes \fI&hook\fR from the \f(CW\*(C`parent\*(C'\fR hook list.
.SS "POSIX::AtFork\->delete_from_child(\e&hook)"
.IX Subsection "POSIX::AtFork->delete_from_child(&hook)"
