Munin::Common::Timeout(3)                  User Contributed Perl Documentation


Munin::Common::Timeout - Run code with a timeout. May nest.


use Munin::Common::Timeout; do_with_timeout(50, sub { # ... do_with_timeout(5, sub { # ... # ... }); # ... });


See also Time::Out, Sys::AlarmCall


do_with_timeout my $finished_with_no_timeout = do_with_timeout($seconds, $code_ref) or die "Timed out!"; Executes $block with a timeout of $seconds. Returns the return value of the $block if it completed within the timeout. If the timeout is reached and the code is still running, it halts it and returns undef. NB: every $code_ref should return something defined, otherwise the caller doesn't know if a timeout occurred. Calls to do_with_timeout() can be nested. Any exceptions raised by $block are propagated. perl v5.20.3 2015-11-05 Munin::Common::Timeout(3)
