No, I don't think so.  function() may return any non-zero value to be true.
 If it returned 2, your if would fail.

Much better is:

i = function(parm);
if (i) /* ... */

I don't see what the fascination is with cramming everything into a single
statement.  C just isn't built properly for that.

Perl, however, ... ;-)
