Based on my experience with SPDK, I believe this would get messy
very quickly.
For example, a common usage is to redefine close to _close.
If the application is going to use sockets without requiring changes,
then a fake fd is needed to represent a socket and close has to
handle it as well ... which will clash with the 'simplistic' redefinition
to _close, so we'd need some way of turning these on/off
individually.
I think there are really only two models that are viable - either an
external POSIX layer that is used by everything (in the general case,
Cygwin would be an example), or a private implementation that is
not exposed publicly.
Keeping the implementation private is not just about keeping
POSIX out of the headers. It's about avoiding conflicts with the
application; e.g. making sure that any signal implementation can
co-exist with the application.
Regards,
Nick
