blocking If the message is too large to fit in the queue, your script will wait until another process reads messages from the queue and frees enough space for your message to be sent. This is called blocking; you can prevent blocking by setting the optional parameter to false, in which case will immediately return false if the message is too big for the queue, and set the optional to , indicating that you should try to send your message again a little later on. blocking``msg_send``error_code``MSG_EAGAIN
