NAME

       io_uring_prep_poll_remove - prepare a poll deletion request

SYNOPSIS

       #include <liburing.h>

       void io_uring_prep_poll_remove(struct io_uring_sqe *sqe,
                                      __u64 user_data);

DESCRIPTION

       The io_uring_prep_poll_remove(3) function prepares a poll removal
       request. The submission queue entry sqe is setup to remove a poll
       request identified by user_data

       Works like io_uring_prep_cancel(3) except only looks for poll
       requests. Apart from that, behavior is identical.  See that man
       page for specific details.

RETURN VALUE

       None

ERRORS

       These are the errors that are reported in the CQE res field. On
       success, 0 is returned.

       -ENOENT
              The request identified by user_data could not be located.
              This could be because it completed before the cancelation
              request was issued, or if an invalid identifier is used.

       -EINVAL
              One of the fields set in the SQE was invalid.

       -EALREADY
              The execution state of the request has progressed far
              enough that cancelation is no longer possible. This should
              normally mean that it will complete shortly, either
              successfully, or interrupted due to the cancelation.
