 Takes as its first argument the C<%SIG> hash and returns a hash reference that represent the current state of the receiver. C<%SIG>'s fields C<'USR1'> and C<'USR2'> will be replaced by the receiver's callbacks. C<cb> specifies the callback to trigger each time a complete message has arrived. Basically, you want to use it like this :
 
-    my $rv = mrecv local %SIG, cb => sub { ... };
+    my $rcv = mrecv local %SIG, cb => sub { ... };
 
 In the callback, C<$_[0]> is the sender's PID (or C<0> if the sender wanted to stay anonymous) and C<$_[1]> is the message received.
