How to enclose a quoted variable in quotes I want to call: `./mjpg_streamer -i "./input_uvc.so -r 320x240" -o "./output_http.so -w ./www"` from a C program, running `system()`. The problem is that I have to enclose shell command in quotes, which arleady exist. How can I fix this?

use the escape character `\` like this:


./mjpg_streamer -i \"./input_uvc.so -r 320x240\" -o \"./output_http.so -w ./www\"
