Can't read from stream

Hi,

when I execute the following code, BlitzMax prints this error message: Error reading from stream. What's wrong?

I think you have to use "recvfrom_" when using udp-sockets:

Edit: This seems to work:

...

While MilliSecs()-TempTime < timeout

   If UDP.ReadAvail() > 0 Then
   
      Print (UDPReadByte(UDP))
   
   End If 

Wend

Print "Timeout"

CloseStream(Stream)
CloseSocket(UDP)

Function UDPReadByte:Int(Socket:TSocket)
	Local buf:Byte
	Local sender_ip:Int, sender_port:Int
	recvfrom_ ..
		Socket._socket, Varptr buf, 1, .. ' sockethandle, buffer, buffersize
		0, .. ' flags
		sender_ip, sender_port
		
	Return buf
EndFunction
