rte_posix_osadapter_socket_ops()

const rte_os_socket_ops_t * rte_posix_osadapter_socket_ops

(

void

)

The POSIX raw OS socket operations vtable (UDP and TCP).

open returns a non-blocking socket (O_NONBLOCK, OSA rule R5): recv/send on it return RTE_STATUS_TIMEOUT instead of blocking; set_nonblocking(false) switches it to blocking. If O_NONBLOCK cannot be set, open closes the socket, leaves *out_handle unwritten and returns RTE_STATUS_INTERNAL_ERROR.

Returns

The adapter's static vtable (never NULL).
