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.
