NAME

NanoMsg::Raw::Message - Message buffer for NanoMsg::Raw

SYNOPSIS

            

              
              
use NanoMsg::Raw;
{
    my $msg = nn_allocmsg(3, 0);
    $msg->copy('foo');
    nn_send($sock, $msg);
}
{
    nn_recv($sock, my $buf);
    warn $buf;
}
            
          

DESCRIPTION

Instances of this class represent a message buffer allocated by nanomsg. New empty buffers can be allocated using nn_allocmsg. Both nn_recv and nn_recvmsg can be used to allocate buffers initialised with the contents of a received message.

NanoMsg::Raw::Messages can be used to send and receive data in a zero-copy fashion.

When using a message instance as a string, its overloading will produce a string containing a copy of the buffer content.

A string pointing to the actual buffer content, without having to create a copy of it, can be obtained by dereferencing the message instance as a scalar.

copy($data)

            

              
              
$msg->copy('foo');
            
          

Copies $data to the beginning of the buffer. If the data is larger than the space allocated for the buffer, an exception will be thrown.
