39 This module allows you to hook thread destruction without fiddling with the internals of L<threads>.
41 It acts globally on all the threads that may spawn anywhere in your program, with the exception of the main thread.
43 The hooks registered with this module will also be called when pseudo-forks (i.e. processes spawn on Windows for the C<fork> emulation) terminate.
52 Specify that the given block or code reference C<$coderef> will have to be called (in void context, without arguments) every time a thread or a pseudo-fork terminates.
59 For joined threads, it will be called when C<join> succeeds, after any C<END> block local to the spawn thread ;
63 For detached threads, it will be called if and only if the thread terminates before the main thread, and the hook will then fire at global C<END> time ;
67 For pseudo-forks, it will be called when C<waitpid> succeeds, after any local or global C<END> block ;
71 It will never trigger for the destruction of the main thread.
79 sub register (&) { push @callbacks, shift }
81 sub _CLEANUP { $_->() for @callbacks }
92 This module may happen to build with a C++ compiler as well, but don't rely on it, as no guarantee is made in this regard.
