[nginx] svn commit: r4795 - trunk/src/os/unix

New Revision: 4795
URL: http://trac.nginx.org/nginx/changeset/4795/nginx

Log:
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.
