io_uring_prep_poll_remove - prepare a poll deletion request
#include <liburing.h>
void io_uring_prep_poll_remove(struct io_uring_sqe *sqe,
__u64 user_data);
The 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.
None
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.
