Reading whole text files

P: n/a
Cheerio,
I would appreciate opinions on the following:

Given the task to read a _complete_ text file into a string:
What is the "best" way to do it?
Handling the buffer is not the problem -- the character
input is a different matter, at least if I want to remain within
the bounds of the standard library.

Essentially, I can think of three variants:
- Low: Use fgetc(). Simple, straightforward, probably inefficient.
- Default: Use fgets(); ugly, if we are not interested in lines
and have many newline characters to read.
- Interesting: fscanf("%"XSTR(BUFLEN)"c%n", curr, &read), where
XSTR(BUFLEN) gives me BUFLEN in a string literal.

From the labels, it is pretty obvious that I would favour the
last one, so there is the question about possible pitfalls
(yes, I will use the return value and "read") and whether there
are environmental limits for BUFLEN.
If I missed some obvious source (looking for the wrong sort of
stuff in the FAQ and google archives), then please point me
toward it :-)
Regards,
Michael

Also there is no need for a blank after the '>' _unless_ this is
the initial quoting of the line.


Are we running out of spaces again? Someone please memcpy some
more and share them.


That is simply a move to prevent quotes falling off the right and
getting wrapped by poorer software.


Better to insert more spaces and show up the people who over-quote
(except in a cascade, anything with over 4 levels of quoting is probably
worth deleting).
