Public Member Functions
void	ipc_server_handle_client_connected (struct ipc_server *vs, xrt_ipc_handle_t ipc_handle)
	Called when a client has connected, it takes the client's ipc handle.
void	ipc_server_handle_failure (struct ipc_server *vs)
	Perform whatever needs to be done when the mainloop polling encounters a failure.
void	ipc_server_handle_shutdown_signal (struct ipc_server *vs)
	Perform whatever needs to be done when the mainloop polling identifies that the server should be shut down.
int	ipc_server_stop (struct ipc_server *s)
	Asks the server to shut down, this call is asynchronous and will return immediately.

Detailed Description

Main IPC object for the server.

Member Function Documentation

ipc_server_stop()

int ipc_server_stop

(

struct ipc_server *

s

)

Asks the server to shut down, this call is asynchronous and will return immediately.

Use callbacks to be notified when the server stops.

Field Documentation

callback_data

void* ipc_server::callback_data

User data passed to callbacks.

callbacks

const struct ipc_server_callbacks* ipc_server::callbacks

Callbacks for server events.

Referenced by ipc_server_main_common().

id_generator

uint32_t ipc_server::id_generator

Generator for IDs.

no_stdin

bool ipc_server::no_stdin

Disable listening on stdin for server stop.

Referenced by ipc_server_main_common().

process

struct u_process* ipc_server::process

Handle for the current process, e.g. pidfile on linux.

start_of_time_timestamp_ns

int64_t ipc_server::start_of_time_timestamp_ns

Global start of time timestamp.

XrTime that is returned to apps start from this timestamps (with an per app offset applied). In order to ensure that all timestamps for events and other data that is tracked by the runtime within the valid range of XrTime it is offset to be 42 minutes in the past from start of the runtime.

Used to get all the client's xrt_instance::startup_timestamp, to be close to each other but not exactly the same, which is then used to be the base of that app's XrTime start of time.

xso

struct xrt_space_overseer* ipc_server::xso

Space overseer.

Referenced by ipc_server_init_system_if_available_locked().

xsys

struct xrt_system* ipc_server::xsys

The XRT interfaces level system.

Referenced by ipc_server_init_system_if_available_locked().

xsysc

struct xrt_system_compositor* ipc_server::xsysc

System compositor.

Referenced by ipc_server_init_system_if_available_locked().

xsysd

struct xrt_system_devices* ipc_server::xsysd

System devices.
