Is there a rough equivalent to the Linux/Unix stdio.h popen() function in the Win32 API? If so, where can I find it?
Edit: I need to know this to patch an omission in the D standard library. Any answer must use only standard Win32 API, no MSVC-specific functions. Also, I'd prefer something that's not horribly low-level, if it exists.

_popen works properly in a console application. To create a Windows application that redirects input and output, see Creating a Child Process with Redirected Input and Output in the Windows SDK.
DESCRIPTION. The popen() function shall execute the command specified by the string command. It shall create a pipe between the calling program and the executed command, and shall return a pointer to a stream that can be used to either read from or write to the pipe.
MSDN explains how you do what popen does using the Windows API in Pipe Handle Inheritance . Here it provides a well-documented example. It's way more low-level than the _popen function found in the runtime library linked by Jason, but uses the Win32 API exclusively.

You can call _popen if you're writing a console application. For more information, see the documentation on the MSDN site: http://msdn.microsoft.com/en-us/library/96ayss4b(VS.80).aspx
