It uses both signals "SIGUSR1" and + "SIGUSR2", so you won't be able to keep them for something else when you + use this module. + + But, seriously, use something else for your IPC. :) + +FUNCTIONS + "msend" + msend $msg, $pid [, $speed ] + + Sends the string $msg to the process $pid (or to all the processes @$pid + if $pid is an array ref) at $speed bits per second. Default speed is + 1000, don't set it too low or the target will miss bits and the whole + message will be crippled. + + "mrecv" + mrecv $callback + + Takes as its sole argument the callback triggered when a complete + message is received, and returns two code references that should replace + SIGUSR1 and SIGUSR2 signal handlers. Basically, you want to use it like + this : + + local @SIG{qw/USR1 USR2/} = mrecv sub { ... }; + +EXPORT + This module exports on request its two only functions, "msend" and + "mrecv". + +DEPENDENCIES + POSIX (standard since perl 5) and Time::HiRes (standard since perl + 5.7.3) are required. + +SEE ALSO + perlipc for information about signals. + + For truely useful IPC, search for shared memory, pipes and semaphores. + +AUTHOR + Vincent Pit, "" + + You can contact me by mail or on #perl @ FreeNode (Prof_Vince). + +BUGS + Please report any bugs or feature requests to "bug-ipc-morsesignals at + rt.cpan.org", or through the web interface at + .
