From: Julia Lawall <[email protected]> Return a negative error code on failure.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e1,e2; @@ ( if (\(ret < 0\|ret != 0\)) { ... return ret; } | ret = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> The patch also removes a newly unnecessary initialization of err, replaces spaces by a tab, and pulls an assignment out of a conditional test expression.
