The submission queue entry +.I sqe +is setup to place the socket file descriptor pointed by +.IR sockfd +into a state to accept incoming connections. The parameter +.IR backlog , +defines the maximum length of the queue of pending connections. + +This function prepares an async +.BR listen (2) +request.
