Class
ALSACtlElemValue
Description [src]
class ALSACtl.ElemValue : GObject.Object {
parent_instance: GObject
}A GObject-derived object to express the container of array for values specific to element type.
A ALSACtlElemValue includes several types of array for values specific to element type. The
arrays shares the same internal storage, thus the user application should decide the type of
array according to the type of element when accessing to the array. The object is used for the
call of alsactl_card_write_elem_value() and alsactl_card_read_elem_value().
The object wraps struct snd_ctl_elem_value in UAPI of Linux sound subsystem.
