Capture an image from a webcam “still pin”?

Question

I'm looking for a way to capture a still image
from a webcam without streaming video from it.
(I have a USB bandwidth limitation and starting video will fail)

I could not find any examples how to read from a webcam's “still pin”.
C++ or C# code for Windows would be very helpful.
Thanks.
