The step size means that the string must be (minimum + N * step) characters long for -N >= 0. These lengths do not include the terminating zero, so in order to +N ≥ 0. These lengths do not include the terminating zero, so in order to pass a string of length 8 to &VIDIOC-S-EXT-CTRLS; you need to set the <structfield>size</structfield> field of &v4l2-ext-control; to 9. For &VIDIOC-G-EXT-CTRLS; you can -set the <structfield>size</structfield> field to <structfield>maximum</structfield>+1. +set the <structfield>size</structfield> field to <structfield>maximum</structfield> + 1. Which character encoding is used will depend on the string control itself and should be part of the control documentation.</entry> </row> |
