Well today i planned to add some additional features to my HDR camera source, such as passing runtime commands HDR to Non HDR while streaming from application. while checking at header files i found their is no inbuilt api for this. so i thought of creating my own ioctl api to do this job. but after looking at header files i'm confused alot. how to proceed where to add new ioctl api. what are the thing i have consider while doing this.
i have two create two ioctl api - one for HDR and one for NON-HDR. like on/off.
please this kind a new for me if anyone can help i will be happy.
