EAPI const char *eina_stringshare_add_length(const char *str, unsigned int slen) EINA_WARN_UNUSED_RESULT;
eina gets lots of gcc attributes to its api. this should help with optimizations and code correctness, please see "info gcc" for detailed explanation on these. if you experience some functions not working as expected, please double check if they're not marked with EINA_PURE or EINA_CONST, maybe I misused them. Remove the macro and try again. brief explanation: * EINA_WARN_UNUSED_RESULT: if you forgot to use the return of some function, it will emit a warning (and -Werror will make it an error). This way it will be harder to miss the attribution "l = eina_list_append(l, v)". * EINA_ARG_NONNULL(index, index...): if you give it an explicit NULL argument, or some tool (ie: clang) finds it could get a NULL but this is not accepted by API, then a warning will be emitted. This will help those that still use eina_hash_add() as if it is evas_hash_add(). * EINA_MALLOC: any non-NULL pointer it returns cannot alias any other pointer valid when function returns. * EINA_PURE: function have no effects other than the return and this return just depend on parameters and/or globals. You might call this function in a loop a thousand times and it will return the same value, thus you may move this function outside the loop and remove it. * EINA_CONST: stricter version of EINA_PURE, it will not check for global parameters, that is, you cannot consider pointer arguments. Use it for math things like "int sqrt(int)". * EINA_PRINTF(fmt, arg): will check format parameter specified in position "fmt" and passed arguments starting at position "arg", it will check for things like giving integers where short or strings were expected. * EINA_SCANF(fmt, arg): similar to eina_printf(). * EINA_FORMAT(fmt): for use with things like dgettext(), it will get a printf-like format string and modifies it. Please review and test it with your software, make sure you make clean before you install the new version so it has any effect. If you find some functions are missing EINA_WARN_UNUSED_RESULT and EINA_ARG_NONNULL or others, please add them. SVN revision: 38323
