148 | Linux 4.18 introduced another event polling interface, this time using |
|
|
149 | the Linux AIO API. While this API is far superior to epoll and almost |
|
|
150 | rivals kqueue, it also suffers from the same issues as kqueue typically |
|
|
151 | does: only a subset of file types are supported (as of 4.19, I have seen |
|
|
152 | eventfd, pipes, sockets files and some devices, but no ttys). It also |
|
|
153 | is subject arbitrary system-wide limits imposed on it. Therefore, this |
|
|
154 | backend is not used by default, even when it is compiled in, and you have |
|
|
155 | to request it explicitly, e.g. with LIBEV_FLAGS=64. If unsure, accept the |
|
|
156 | default. |
