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 option. Alternatively you can here view or download the uninterpreted source code file. For more information about "get-errno.c" see the Fossies "Dox" file reference documentation and the last Fossies "Diffs" side-by-side code changes report: 3.2.4_vs_3.3.

   28    but doesn't need to test for specific errno values, can use these
   29    functions to avoid namespace pollution.  For example, a file that
   30    defines EQUAL should not include <errno.h>, since <errno.h> might
   31    define EQUAL; such a file can include <get-errno.h> instead.  */
