Subject: Add (void) on our uses of the swrite() macro when we don't read the return
X-Git-Tag: upstream/7.37.1~14845
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ffe5c462247ca9854ba981debe9559e2f00bb211;p=platform%2Fupstream%2Fcurl.git

Add (void) on our uses of the swrite() macro when we don't read the return
code as this makes compiler warnings. We *should* fix the code to deal with
the return codes instead...
