But for me I'm having issues where not all the names come back, and instead only some of them do. Some others are just not received and I'm unsure as to why that would be happening even though the select() function is present and should be able to handle the availability of sockets for when they are readable. The number of names which come back is also different every time the stations are run, which is making me think that maybe the issue lies with the blocking nature of receiving datagrams (despite select()) Would you know why this is occuring?
