libuv is a multi-platform support library with a focus on asynchronous I/O. It
was primarily developed for use by [Node.js][], but it's also
used by [Luvit](http://luvit.io/), [Julia](http://julialang.org/),
[pyuv](https://github.com/saghul/pyuv), and [others](https://github.com/libuv/libuv/wiki/Projects-that-use-libuv).

### `-fno-strict-aliasing`
It is recommended to turn on the `-fno-strict-aliasing` compiler flag in
projects that use libuv. The use of ad hoc "inheritance" in the libuv API
may not be safe in the presence of compiler optimizations that depend on
strict aliasing.
MSVC does not have an equivalent flag but it also does not appear to need it
at the time of writing (December 2019.)
### AIX Notes

### z/OS Notes
z/OS compilation requires [ZOSLIB](https://github.com/ibmruntimes/zoslib) to be installed. When building with [CMake][], use the flag `-DZOSLIB_DIR` to specify the path to [ZOSLIB](https://github.com/ibmruntimes/zoslib):
```bash
$ (cd build && cmake .. -DBUILD_TESTING=ON -DZOSLIB_DIR=/path/to/zoslib)
$ cmake --build build
```
z/OS creates System V semaphores and message queues. These persist on the system
after the process terminates unless the event loop is closed.

If one of the events `UV_READABLE` or `UV_WRITABLE` are set, the
callback will be called again, as long as the given fd/socket remains
readable or writable accordingly. Particularly in each of the following
scenarios:
* The callback has been called because the socket became
readable/writable and the callback did not conduct a read/write on
this socket at all.
* The callback committed a read on the socket, and has not read all the
available data (when `UV_READABLE` is set).
* The callback committed a write on the socket, but it remained
writable afterwards (when `UV_WRITABLE` is set).
* The socket has already became readable/writable before calling
:c:func:`uv_poll_start` on a poll handle associated with this socket,
and since then the state of the socket did not changed.
In all of the above listed scenarios, the socket remains readable or
writable and hence the callback will be called again (depending on the
events set in the bitmask). This behaviour is known as level
triggering.
