2020-08-20examples/io_uring-test: don't error on shorter filesJens Axboe
The example currently assumes the file is at least 4*4096 bytes, and errors when we get 0 reads on EOF. Fix this up. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2019-07-24src/Makefile: keep private headers in <liburing/*.h>Stefan Hajnoczi
It is not possible to install barrier.h and compat.h into the top-level /usr/include directly since they are likely to conflict with other software. io_uring.h could be confused with the system's kernel header file. Put liburing headers into <liburing/*.h> so there is no chance of conflicts or confusion. Existing applications continue to build successfully since the location of <liburing.h> is unchanged. In-tree examples and tests require modification because src/liburing.h is moved to src/include/liburing.h.

2019-06-13example/io_uring-test.c: Fix iovecs incrementStephen Bates
This example misses an increment though the iovecs array. This causes the same buffer to be filled from the block device every time. It would be good to fix this since it is one of the first examples a new-comer to io_uring is exposed too.

2019-04-18Rename completion helpersJens Axboe
We have io_uring_get_sqe() on the submission side, yet the completion side is named _completion. Rename as follows: io_uring_get_completion() io_uring_peek_cqe() iO_uring_wait_completion() io_uring_wait_cqe() This better tells the user what the _get variant does by calling it _peek instead, and we move to using _cqe() as the postfix instead of _completion.
