NAME

       io_uring_prep_listen - prepare a listen request

SYNOPSIS

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

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

DESCRIPTION

       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

       None

ERRORS

       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.
