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