What you have to do is (I cannot check myself as I'm not using
ECL currently)
- not close the process handle pr_info.hProcess (this probably
means adding a top-level variable to store it, let's call it
childHandle)
- use something like:

int status; /* just in case you'd need the exit status */
WaitForSingleObject(childHandle, INFINITE);
/* skip the following if you don't care about the exist status */
GetExitCodeProcess(childHandle, (LPDWORD)&status);
CloseHandle(childHandle);
