Maybe you should get a book to learn "C"?
The macro uses "goto" which won't work with inline functions in that
situation.
Since the macro uses the only argument exactly once, it actually makes
no functional/semantic difference if it is a macro or would be an inline
function (and performance-wise very probably too with any somewhat
recent compiler).
And the macro just avoids to copy-paste identical lines/logic.

And you surely should learn to quote correctly and thus avoid top
posting completely.
