Thread: CreateProcess and console handles

Hello, everyone! I hope you can help me with this one...
What I want to do is create a console application that would process user input and then spawn other console applications in the same console window. So I write something like this:

Code:

	PROCESS_INFORMATION processInfo;
	STARTUPINFO startupInfo;
	char userInput[100];

	ZeroMemory(&startupInfo, sizeof(startupInfo));
	startupInfo.cb = sizeof(startupInfo);

	if(CreateProcess(NULL, "ls.exe",
		NULL,NULL,FALSE,0,NULL,
		NULL,&startupInfo,&processInfo))
	{ 
		WaitForSingleObject(processInfo.hProcess,INFINITE);
		CloseHandle(processInfo.hThread);
		CloseHandle(processInfo.hProcess);
	}  

	printf("What do you do?\n" ); // Works OK
	gets(userInput); // Freezes here!
	printf("Got it!\n" );

The problem is, after the spawned process ends, the console stops receiving keyboard input (the output still works). I used to think that the child process closes the input handles when it finishes, but I realised that bInheritHandles parameter to CreateProcess() is set to FALSE, so that's not what causes the freeze. What can I do about it?

You can try other ways to get keyboard input, getline, cin<< etc.
And are you sure it works before the process?
