Subject: Ignore return value from fwrite when writing debug log
X-Git-Tag: v3.5.1~15
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a0f7c10567b041079eef7aab8055091c79b4049b;p=thirdparty%2Fccache.git

Ignore return value from fwrite when writing debug log

This silences some compilers’ warnings about ignoring return value of
fwrite.

There’s not much we can do if they fail, and it’s also not important
enough to e.g. call failed() for the debug logs.
