io_uring_prep_poll_remove(3) liburing Manualio_uring_prep_poll_remove(3)
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 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.
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.
