You can specify multiple property-value pairs by delimiting them with a comma as follows:
name1, &value1, name2, &value2,...For example, you can get values in the following manner:
camera_get_photovf_property( camera_handle, CAMERA_IMGPROP_WIDTH, &vf_width, CAMERA_IMGPROP_HEIGHT, &vf_height, CAMERA_IMGPROP_ROTATION, &vf_rotation, CAMERA_IMGPROP_BURSTMODE, &burstmode, CAMERA_IMGPROP_FRAMERATE, &framerate, CAMERA_IMGPROP_HWOVERLAY, &hwoverlay, CAMERA_IMGPROP_ZOOMFACTOR, &zoomfactor );
