Function Documentation

get_ism()

static struct ipc_shared_memory * get_ism ( volatile struct ipc_client_state *  ics )

inlinestatic

Get the data in the shared memory of the given client.

References ipc_client_state::server.

get_ism_handle()

static xrt_shmem_handle_t get_ism_handle ( volatile struct ipc_client_state *  ics )

inlinestatic

Get the handle for the shared memory of the given client.

ipc_server_client_destroy_session_and_compositor()

void ipc_server_client_destroy_session_and_compositor

(

volatile struct ipc_client_state *

ics

)

This destroys the native compositor for this client and any extra objects created from it, like all of the swapchains.
