>+.Sh DESCRIPTION
>+The
>+.Fn pthread_atfork
>+function declares fork handlers to be called before and after
>+.Xr fork 2 ,
>+in the context of the thread that called
>+.Xr fork 2 .
>+The
>+.Fa prepare
>+fork handler will be called before
>+.Xr fork 2
>+processing commences.
>+The
>+.Fa parent
>+fork handle will be called after
>+.Xr fork 2
>+processing completes in the parent process.
>+The
>+.Fa child
>+fork handler will be called after
>+.Xr fork 2
>+processing completes in the child process.
>+If no handling is desired at one or more of these three points, the
>+corresponding fork handler address(es) may be set to NULL.

>+The order of calls to 
>+.Fn pthread_atfork
>+is significant.
>+The
>+.Fa parent
>+and

>+fork handlers will be called in the order in which they were 
>+established by calls to
>+.Fn pthread_atfork .
>+The
>+.Fa prepare
>+fork handlers will be called in the opposite order.
>+.Sh RETURN VALUES
>+Upon successful completion,
>+.Fn pthread_atfork
>+returns a value of zero; otherwise, an error number is returned
>+to indicate the error.
