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.
