Most linuxes today use the UVC driver to control webcams. You might want to take a look at the UVC driver documentation in the linux kernel source code: Documentation/video4linux/uvcvideo.txt. Most userspace tools will use the v4l2 interface i.e. /dev/videoX device.

Here's an example I found with a quick search: **broken link removed**

For a more detailed code I recomment you download and look at the source code of one of the open source webcam projects i.e. Fswebcam.
