Getting Thread Exit Code

[masnu]

I have created a worker thread to connect to a data server. The thread needs to wait a few seconds and exit if no data arrives (i.e. server is not online). I need to trap the thread exit code so my main thread can know if the workher thread terminated with an error. I have the following code: static UINT Connect(void* p_this); UINT Connect(); UINT Client::Connect(void* p_this) { Client* pClient = (Client*)p_this; pClient->Connect(); } UINT Client::Connect() { CDataServer pServer = new CDataServer(); ........ int nError = pServer->Connect(); if ( nError != 0 ) //Error connecting to server return nError; ....... } From the documentation I know I can use GetExitCodeThread to get the error code but where is the best place to put this? Should I post an exit message to the main thread and read the code there? Are there any other solutions that would be better? Thanks.

What error? Use of thread exit codes are most often replaced with a form of communication of your own design. You are doing Object Oriented Programming aren't you?

The exit code I want is the one I have defined as nError in the above example. Based on that number I can determine why the thread exited.

From your code, I can say that you need: 1. return the error code in your thread function Connect(void* param) 2. From the main thread you can call GetExitCodeThread Better solution is something like Mike suggested, define an interface to receive the error or success is much better.

Your assumption is correct. You can return nError and then read that number via GetExitCodeThread from the main thread. :)
