The GNU coding standards have had these two items since the beginning.
First:
Don't use the return value of @code{sprintf}. It returns the number of
characters written on some systems, but not on all systems.
I don't see this mentioned in the Gnulib entry for sprintf at
http://www.gnu.org/software/gnulib/manual/html_node/sprintf.html
Is it still relevant?
Second:
Be aware that @code{vfprintf} is not always available.
Again, I don't see it mentioned in
http://www.gnu.org/software/gnulib/manual/html_node/vfprintf.html
though seemingly nearly every other system has some kind of problem.
Is it still relevant?
(Reuben and I are trying to rewrite that node among others.)
Thanks,
