rcp_set_list_relative()

rcp_error_t rcp_set_list_relative	(	rcp_camera_connection_t *	con,
		rcp_param_t	id,
		int32_t	offset
	)

Set list (by value) with relative offset.

This is not like rcp_set_list which changes the entire list, instead this is like calling rcp_set_int, rcp_set_uint, or rcp_set_str on a parameter based on the relative entry in its list.

For example, to set the ISO to the next (higher value) in the list call:

rcp_set_list_relative(con, RCP_PARAM_ISO, 1);

to set the ISO to the previous (lower value) in the list call:

rcp_set_list_relative(con, RCP_PARAM_ISO, -1);

Parameters

[in]	con	the camera connection
[in]	id	the RCP parameter
[in]	offset	offset to the current index of the list

Returns

RCP_SUCCESS on success.
