How to wait for a process to finish C++

Question

I am creating a process with that code:

CreateProcess(NULL, "process.exe", NULL, NULL, TRUE, 0, NULL, NULL, %ini_processo, %processo_info);

I need my code to wait for my process to finish before resuming. What is the method with C++ ?

WaitForSingleObject(processo_info.hProcess, INFINITE). Don't forget to CloseHandle() the returned handles. And it looks like you ought to be using the Process class if % actually compiles. Use & otherwise. — Hans Passant, Feb 26 '12 at 14:51
Thank you. I begun to learn C++ a week ago and been searching for this solution since yesterday. — 01BTC10, Feb 26 '12 at 14:58

You just call WaitForSingleObject on the handle CreateProcess returns.
