You can achieve the same with:
readf(" %s\n", &s2);
My goal however, is not to read one line of information.
Rather, it is to
read multiple lines of information from standard input. I get
close to
being able to do so if i don't including "\n" as a part of my
format string
or if I changing your suggestion to
while (!stdin.eol()) {
s2 = chomp(readln());
}
but again I run into the predicament was before, a need to
close the
the stream with Ctrl-D/Ctrl-Z.
I made the decision for the current behavior while implementing
readf. Basically I tried to avoid what I think was a mistake of
scanf, i.e. that of stopping string reading at the first
whitespace character, which is fairly useless.
Couldn't the state of stdin be checked upon entrance into readf
and reopened if it is already closed?
Wouldn't that accomplish the desired effect while avoiding
the pitfalls of scanf?
Over the years scanf was improved with %[...] which allows
reading strings with any characters in a set.
Anyway, if I understand correctly, there's no way to achieve
what you want unless you read character-by-character and define
your own control character. There's no out-of-band character
that means "end of this input, but not that of the file".
