[False Prophet]

I'm trying to eject a loaded DLL using FreeLibraryAndExitThread API but I don't understand what the ExitCode parameter is supposed to be. The MSDN isn't very descriptive on this part.

The exit code is a user defined value. When a thread exits, it is possible to retrieve the exit code by calling GetExitCodeThread(), and from there do handling.

In most languages you typically return 0 or EXIT_SUCCESS to indicate success and 1 or EXIT_FAILURE to indicate failure. In fact usually any non-zero return indicates failure. As sponge said it is also common to use a user defined value. So returning a number other than 0 indicates something in particular. It can be used similar to how error codes are used in Get/SetLastError()
