NAME IPC::MorseSignals - Communicate between processes with Morse signals. VERSION Version 0.17 WARNING Due to the POSIX signals specification (which I wasn't aware of at the time I wrote this module), this module is by nature completely unreliable and will never work properly. It is therefore deprecated. Please don't use it (if you were actually crazy enough to use it). SYNOPSIS # In the sender process use IPC::MorseSignals::Emitter; my $deuce = IPC::MorseSignals::Emitter->new(speed => 1024); $deuce->post('HLAGH') for 1 .. 3; $deuce->send($pid); ... # In the receiver process use IPC::MorseSignals::Receiver; local %SIG; my $pants = IPC::MorseSignals::Receiver->new(\%SIG, done => sub { print STDERR "GOT $_[1]\n"; }); DESCRIPTION This module implements a rare form of IPC by sending Morse-like signals through "SIGUSR1" and "SIGUSR2". Both of those signals are used, so you won't be able to keep them for something else when you use this module. * IPC::MorseSignals::Emitter is a base class for emitters ; * IPC::MorseSignals::Receiver is a base class for receivers. But, seriously, use something else for your IPC. :) CAVEATS When the same signal is sent several times in a row to a process, the POSIX standard does not guarantee that the relevant signal handler will be called for each of the notifications. This will result in malformed messages if the transfer speed is so high that the operating system does not have the time to call the signal handler for each bit. DEPENDENCIES You need the complete Bit::MorseSignals distribution. Carp (standard since perl 5), POSIX (idem) and Time::HiRes (since perl 5.7.3) are also required. SEE ALSO IPC::MorseSignals::Emitter, IPC::MorseSignals::Receiver. Bit::MorseSignals, Bit::MorseSignals::Emitter, Bit::MorseSignals::Receiver. perlipc for information about signals in perl. For truly useful IPC, search for shared memory, pipes and semaphores. AUTHOR Vincent Pit, "", . You can contact me by mail or on "irc.perl.org" (vincent).
