Hi, 'man 3 fwrite' doesn't say anything about errno, OTOH 'man 3p fwrite', and 'man 3 fclose' does. The comment about 'fread' in 'man 3 fread' could make someone believe that it doesn't set errno. I don't know what C89 has to say about errno, hence I'm just reporting this to you without sending an actual patch. This is manpages 3.61-1 from Debian unstable, and bottom of the manpage says it is: GNU 2012-03-30 FREAD(3) I've checked man-pages.git, and it is the same situation there.
