blocking a program until a non-Python process terminates

I'm running an .exe in Python, using subProcess.Pope n. The executable
writes data to a file I process later on in the program. Unfortunately,
my program returns the error "no such file...". How do I block
execution until the external executable terminates?

returncode = subprocess.call (cmdline)

2) or:

pipe = subprocess.Pope n(cmdline)
returncode = pipe.wait()

Folks, I'm trying to rewrite a program currently written in a scripting language called Rexx. It accesses the Socket API of a server, that feeds it data in ASCII format, when requested. Trouble is, the CLIENT app is using non-blocking I/O to make the initial connection, and I haven't had much experience with non-blocking I/O (at least at the client level). Can someone point me in the direction of some good examples / tutorials for...

In news:OZ0W9RsdDHA.2432@TK2MSFTNGP10.phx.gbl... I ask the question how I can see if all the data is on the other side of the connection. I got as answer that I should use the blocking property. I tried this I don't see any diffents, I am sending 10Mb and the Send/BeginSend command doesn't wait till the data is on the remotepoint. Can somebody pls. explain this. Regards Robert.

I have been searching and can not seem to find a good example of a working UDP client that listens, but does not block while waiting for data arrival. I am trying to write a client application that needs to listen on several TCP ports and one UDP port. It will send a start signal over UDP and then a repeated status message of a fixed length will be returned from the server. I need to listen to these messages, but I can't stop the...

Hi, I'm using a non-blocking connect to connect to a server. Works fine -- the server gets and accepts the connection. However, once the connection is established, I cannot retrieve either the local or the remote endpoint from the client-side socket. The *really* strange thing is that Socket.LocalEndPoint is null. According to the doc, that's impossible: reading the LocalEndPoint

Hi Does someone knows if fopen() is a non-blocking function in a sense that if there isn't sufficient disk space to open a file in write mode, then the function will not wait but fail?

My blocking TCP server hangs in the Accept method when the client software sometimes gets an error. Are there any ways to stop this blocking in the Accept method so I dont have to restart the server? I would rather not use threading or non-blocking sockets. Using VB.Net 2005.
