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.
