Subject: error.h: make errno number reading easier
X-Git-Tag: v2.0.1~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6f198e818b4357b54664e7425c34cdbfe8a984f6;p=thirdparty%2Flibcgroup.git

error.h: make errno number reading easier

Trying to match error number with enum requires manual effort. Make it
easier by adding a comment with errno for every enum value.
