timerfd() and system call review
The Multicians did the whole mutation thing somewhat
better than we do in the Unix world... they tended to
document first, by writing white papers to get their
algorithms discussed.
After they delivered,they then froze the parameter
list part of the APIs, but they versions-numbered structures
passed as parameters, so one could
- add new elemnts to the end (a compatable change)
- retire old papameters (version change required), or
- change precision of parameter values (version change required).
I've used the same trick on Unix/Linux to avoid having to
have "flag days" and allow several of us (Hi, Edsel!) to
develop in parallel, even when we were changing intarfaces
with wild abandon.
