# zwp_input_timestamps_manager_v1
A global interface used for requesting high-resolution timestamps for input events.Requests
-
void zwp_input_timestamps_manager_v1_destroy(struct zwp_input_timestamps_manager_v1* zwp_input_timestamps_manager_v1)Informs the server that the client will no longer be using this protocol object. Existing objects created by this object are not affected.
-
struct zwp_input_timestamps_v1* zwp_input_timestamps_manager_v1_get_keyboard_timestamps(struct zwp_input_timestamps_manager_v1* zwp_input_timestamps_manager_v1,struct wl_keyboard* keyboard /* the wl_keyboard object for which to get timestamp events */)Creates a new input timestamps object that represents a subscription to high-resolution timestamp events for all wl_keyboard events that carry a timestamp. If the associated wl_keyboard object is invalidated, either through client action (e.g. release) or server-side changes, the input timestamps object becomes inert and the client should destroy it by calling zwp_input_timestamps_v1.destroy.
-
struct zwp_input_timestamps_v1* zwp_input_timestamps_manager_v1_get_pointer_timestamps(struct zwp_input_timestamps_manager_v1* zwp_input_timestamps_manager_v1,struct wl_pointer* pointer /* the wl_pointer object for which to get timestamp events */)Creates a new input timestamps object that represents a subscription to high-resolution timestamp events for all wl_pointer events that carry a timestamp. If the associated wl_pointer object is invalidated, either through client action (e.g. release) or server-side changes, the input timestamps object becomes inert and the client should destroy it by calling zwp_input_timestamps_v1.destroy.
-
struct zwp_input_timestamps_v1* zwp_input_timestamps_manager_v1_get_touch_timestamps(struct zwp_input_timestamps_manager_v1* zwp_input_timestamps_manager_v1,struct wl_touch* touch /* the wl_touch object for which to get timestamp events */)Creates a new input timestamps object that represents a subscription to high-resolution timestamp events for all wl_touch events that carry a timestamp. If the associated wl_touch object becomes invalid, either through client action (e.g. release) or server-side changes, the input timestamps object becomes inert and the client should destroy it by calling zwp_input_timestamps_v1.destroy.

# zwp_input_timestamps_v1
Provides high-resolution timestamp events for a set of subscribed input events. The set of subscribed input events is determined by the zwp_input_timestamps_manager_v1 request used to create this object.Requests
-
void zwp_input_timestamps_v1_destroy(struct zwp_input_timestamps_v1* zwp_input_timestamps_v1)Informs the server that the client will no longer be using this protocol object. After the server processes the request, no more timestamp events will be emitted.
Events
-
uint32_t tv_sec_hi /* high 32 bits of the seconds part of the timestamp */uint32_t tv_sec_lo /* low 32 bits of the seconds part of the timestamp */uint32_t tv_nsec /* nanoseconds part of the timestamp */The timestamp event is associated with the first subsequent input event carrying a timestamp which belongs to the set of input events this object is subscribed to. The timestamp provided by this event is a high-resolution version of the timestamp argument of the associated input event. The provided timestamp is in the same clock domain and is at least as accurate as the associated input event timestamp. The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999].
