Detailed Description

The XRT representation of XrSession, this object does not have all of the functionality of a session, most are partitioned to the session level compositor object.

Often this is xrt_compositor_native, note that interface may also be a system level object depending in implementer.

Member Function Documentation

xrt_session_destroy()

static void xrt_session_destroy ( struct xrt_session **  xs_ptr )

inlinestatic

Destroy an xrt_session - helper function.

Parameters

[in,out]

xs_ptr

A pointer to the xrt_session struct pointer.

Will destroy the system if *xs_ptr is not NULL. Will then set *xs_ptr to NULL.

References destroy.

static XRT_CHECK_RESULT xrt_result_t xrt_session_poll_events ( struct xrt_session *  xs, union xrt_session_event *  out_xse  )

inlinestatic

Poll a single event from this session, if no event is available then the type of the event will be XRT_SESSION_EVENT_NONE.

Parameters

	xs	Pointer to self
[out]	out_xse	Event to be returned.

Helper for calling through the function pointer.

References poll_events.
