global variable question (socket)

[sstoica]

Hello,

Here is my n00b question for the day. I have 2 libraries like this:

lowLevelLib.py

from socket import *

def connectUdp(host, port):
    """connectUdp(host,port)

    Create an UDP socket and connect to host and port. Return the
    socket and 1/0 if connection was succesfull.
    """
	try:
		udpsocket = socket(AF_INET, SOCK_DGRAM)
		udpsocket.connect( (host, port) )
		#udpsock.setblocking(0)

	except Exception, ex:
		#do something
                udpsocket.close()
                udpsocket = None
		return None, 0
	
        return udpsocket, 1

highLevelLib.py

import lowLevelLib.py

class server():
	
	self.udpScoket = None
	self.udpState = "closed"
""" 
	__init__ + other methods 
"""
    def openUdp(self):
        
         self.udpSocket, connectOK = lowLevelLib.connectUdp(self.connection.host(), self.connection.udpPort())
	if connectOK:
            self.udpState == "connected"
        #else:
            #self.udpSocket = None
            #self.udpState = "closed"
     
    def closeUdp(self):
	if udpState == "connected":
		udpSocket.close()
		udpSocket = None

Ok, now if the connection is succesfull (the socket is created and connects to the host) i will pass the socket that i created to my highLevelLib. Can i be sure that after i use highLevelLib.closeUdp() the socket is destroyed for good? I am pretty sure it is, i mean i free the phone's memory, but i want a second opinion. I don't know how to check this in symbian.

Thanks

In theory, yes. There has been some reported problems with the current socket implementation of PyS60 with closing and such. The best way to find out is to test this, right?

it seems to work ^^ thanks miohtama for your reply
