Libraries seem to have detoriated thus, in that, i think compiling
on a twenty year old system will currently really fail, also
because of snprintf for example. (Originally there was a "lazy
wrapper" which simply called vsprintf().)
But it is on the list and not forgotten.
I would advise not to waste time and brain cycles for open source on
getting network-related code -- or generally code that needs to support
inputs you don't control -- to run on 20-year-old systems with
insufficient library support that make you write 20 lines of situation
and error checking for a job you get done with three in a modern variant
of your programming language and one in another. We've seen mutt
maintainers come and go over the years.
That standard format I/O, for example, i never liked, i will
port the "format codec", one day. (Just a(n) (restartable)
object that does it, being fed from the front instead of
calling pointer-to-function from the back, as some I/O libraries
implemented the *f() series, at one time, at least. With it,
non-restartable (eg stack buffer) is then simply
Txt::FormatDecoder fd;
...
if(_cplen == M1::ui4)
_cplen = length(_cp);
(void)fd.setup(_cp, _cplen, _fmt, _valistp)
.setRestartable(fal0)
.call();
_cplen = ((fd.isFinished() || 0 != fd.numberOfConversions())
? fd.numberOfAssignments()
: M1::ui4);
return _cplen;
which is so much better than anything else thinkable.)
Wasting time on solved problems seems to be a hobby project in itself,
but not useful if you don't have it now but want your application (such
as mutt) written and progress.
