As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) C and C++ source code syntax highlighting (style: standard
) with prefixed line numbers and code folding
Alternatively you can here view
the uninterpreted source code file.
For more information about "get-errno.c" see the Fossies "Dox" file reference
documentation and the last Fossies "Diffs"
