Detailed Description

A helper to implement a xrt_system, takes care of multiplexing events to sessions.

Member Function Documentation

static void u_system_destroy ( struct u_system ** usys_ptr )

inlinestatic

Destroy an u_system_create allocated u_system - helper function.

Parameters

[in,out] usys_ptr A pointer to the u_system_create allocated struct pointer.

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

struct xrt_session_event_sink u_system::broadcast

Pushes events to all sessions created from this system.

uint32_t u_system::count

Number of session and event sink pairs.

struct u_system_session_pair* u_system::pairs

Array of session and event sink pairs.

struct xrt_system_compositor* u_system::xsysc

Used to implement xrt_system::create_session, can be NULL.

This field should be set with u_system_set_system_compositor.

The documentation for this struct was generated from the following file:
