UDPOpen and maintaining multiple open UDP ports

2 posts in this topic

Hello all!

I have a seemingly undocumented and unsearchable question.  Lets say, I use this line frequenlty to send strings to multiple IP hosts and different times

UDPSend((UDPOpen("192.168.10.1", 6789)), "EXAMPLE")

Now, lets say that I used this command multiple times to the same IP address.  What happens to the last "UDPOpen" commands that I used.  Do they remain open still?  Should I be assigning these ports to variables so that I can close each port that I open immediately after I use it?  I ask because I do not want to lock ports up or create a "memory leak" of sorts by creating multiple ports that never get closed.  I appreciate any help or advice.

Thanks!

Always open and close network connections.

When you try this:

TCPStartup()

Global $aUDP

$aUDP = UDPOpen("192.168.10.1", 6789)
ConsoleWrite("Socket: " & $aUDP[1] & @CRLF)
$aUDP = UDPOpen("192.168.10.1", 6789)
ConsoleWrite("Socket: " & $aUDP[1] & @CRLF)

UDPCloseSocket($aUDP) ; only last socket closed


TCPShutdown()
you will see that every time a new socket is created!

Programming today is a race between software engineers striving to
build bigger and better idiot-proof programs, and the Universe
trying to produce bigger and better idiots.
So far, the Universe is winning.
