felspar-io Implementation

The contains three implementations:

POSIX using poll
Windows using WSAPoll
Linux's io_uring

The poll and WSAPoll are similar, but not identical. The main part of the implementation is in:

poll.hpp -- Common header containing completion tracking and common retry and cancellation code.
poll.iops.cpp -- Implementation of the individual IOP APIs.
poll.warden.cpp -- Implementation of the poll loop itself together with other code needed to have everything work.

The differences between poll and WSAPoll are handled through #if blocks.

There is a separate implementation io_uring in the following files:

uring.hpp -- IOP delivery and completion header file.
uring.iops.cpp -- Implementation of the various IOPs.
uring.warden.cpp -- The io_uring submission and completion loop.

Other files

convenience.cpp -- Contains a few helpers.
posix.cpp -- Contains wrappers for some common POSIX APIs.
tls.cpp -- Contains an implementation of TLS using OpenSSL.
warden.cpp -- Common warden code (creating sockets and pipes).
