printf in a multi-threaded console application

Hello,

I have a console application and am using CreateThread to create a new
thread from my main thread. Both threads call printf and, thus, cause
interleaved prints to the console window. Is there a reasonable way to have
the second thread open it's own console window and direct its printfs to
that window? I can't separate them into two separate applications because
they must share common global variables.

Thanks,

first of all use _beginthread instead since
CreateThread doesnt support the c-runtime library.

sure you can open as many windows as you want,
rtfm :p

To print it properly, use a synchronizing kernel object such as mutex.

No, a single process can only have one console.

Someone needs to read a little more carefully. The OP asked about opening a
second *console* window. A process can only have one console.
