bool strtolower | ( | char * | str | ) |
Convert a given ASCII string to lowercase.
NOTE: only support ASCII characters, no UTF8 fancy. As currently the function is only used to lowercase data-filenames if they are not found, this is sufficient. If more, or general functionality is needed, look to r7271 where it was removed because it was broken when using certain locales: eg in Turkish the uppercase 'I' was converted to '?', so just revert to the old functionality
