NAME         top

       io_uring_prep_listen - prepare a listen request

SYNOPSIS         top

       #include <sys/socket.h>
       #include <liburing.h>

       void io_uring_prep_listen(struct io_uring_sqe *sqe,
                                 int sockfd,
                                 intbacklog);

DESCRIPTION         top

       The io_uring_prep_listen(3) function prepares a listen request.
       The submission queue entry sqe is setup to place the socket file
       descriptor pointed by sockfd into a state to accept incoming
       connections.  The parameter backlog, defines the maximum length of
       the queue of pending connections.

       This function prepares an async listen(2) request. See that man
       page for details.

RETURN VALUE         top

       None

ERRORS         top

       The CQE 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 -1 on failure and set
       errno to the actual error value, io_uring never uses errno.
       Instead it returns the negated errno directly in the CQE res
       field.
