popen()

I'm trying to do some parsing on netstat's output, but this is proving rather difficult...:

So far, popen() has me baffled. As far as I can tell from the snippit below, popen is returning NULL, and errno is set to zero. (Which makes no sense.) What is going on here?

Code:

	ph = popen("netstat -e", "r");
	if(!ph)
	{
		sprintf(err, "Error is %d. ph = %d\n", errno, ph);
		MessageBox(HWND_DESKTOP, "popen failed.", "popen", MB_OK);
		MessageBox(HWND_DESKTOP, err, err, MB_OK);
		return;
	}
(function continues..., or would, if popen() would succeed...)

Since all I really care about is the bytes sent & recv'd... is there an easier way to get those numbers? Some API call I know nothing about?

Perhaps the health warning here explains.

Note The _popen function returns an invalid file handle, if used in a Windows program, that will cause the program to hang indefinitely. _popen works properly in a Console application. To create a Win

Almost certainly, probably the ones netstat uses itself.

You could use GetIfTable, which will give you the number of bytes sent and received for each interface. Netstat appears to use GetIpStatsFromStackEx, which is undocumented.
