SYNOPSIS

struct v4l2_ctrl * v4l2_ctrl_new_std(struct v4l2_ctrl_handler * hdl, const struct v4l2_ctrl_ops * ops, u32 id, s64 min, s64 max, u64 step, s64 def);

ARGUMENTS

hdl

The control handler.

ops

The control ops.

id

The control ID.

min

The control's minimum value.

max

The control's maximum value.

step

The control's step value

def

The control's default value.

DESCRIPTION

If the v4l2_ctrl struct could not be allocated, or the control ID is not known, then NULL is returned and hdl->error is set to the appropriate error code (if it wasn't set already).

If id refers to a menu control, then this function will return NULL.

Use v4l2_ctrl_new_std_menu when adding menu controls.
