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. See that man page for details. + +.SH RETURN VALUE +None +.SH ERRORS +The CQE +.I res +field will contain the result of the operation. See the related man page for +details on possible values. Note that where synchronous system calls will return +.B -1 +on failure and set +.I errno +to the actual error value, io_uring never uses +.IR errno . +Instead it returns the negated +.I errno +directly in the CQE +.I res +field. +.SH SEE ALSO +.BR io_uring_get_sqe (3), +.BR io_uring_submit (3), +.BR listen (2) -- 2.45.2
