Subject: (write_file): New function.
X-Git-Tag: nettle_1.8_release_20040110~38
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=72ca5b454d7ff90b2951adc07584f563560db561;p=thirdparty%2Fnettle.git

(write_file): New function.
(write_string): Simplified error check, it's no real point in
calling ferror unless we also call fflush.
