Minimum protocol version required for the timestamp function.

Retrieve the interface name (class) of a resource object.

Returns

Interface name of the resource object.

Get the associated client

Returns

the client that owns the resource.

Get the internal ID of the resource

Returns

the internal ID of the resource

Get interface version

Returns

Interface version this resource has been constructed with.

destroy the input timestamps object 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.

Post 'not enough memory' error to the client

If the compositor has not enough memory to fulfill a certail request of the client, this function can be called to notify the client of this circumstance.

Check whether this wrapper actually wraps an object.

Returns

true if there is an underlying object, false if this wrapper is empty

high-resolution timestamp event

Parameters

tv_sec_hi high 32 bits of the seconds part of the timestamp
tv_sec_lo low 32 bits of the seconds part of the timestamp
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].
