get_idev()

static struct ipc_device * get_idev ( volatile struct ipc_client_state *  ics, uint32_t  device_id  )

inlinestatic

Get a idev with the given device_id.

References ipc_client_state::server.

get_xdev()

static struct xrt_device * get_xdev ( volatile struct ipc_client_state *  ics, uint32_t  device_id  )

inlinestatic
