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.
