Subject: Explicitly ignore returned value from unlink() in ngx_open_tempfile().
X-Git-Tag: release-1.3.5~15
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/stylesheets/stylesheet.css?a=commitdiff_plain;h=66e9525e84a2d09269eb766da15df60c5bc0a1dd;p=nginx.git

Explicitly ignore returned value from unlink() in ngx_open_tempfile().

The only thing we could potentially do here in case of error
returned is to complain to error log, but we don't have log
structure available here due to interface limitations.
