| |
From: Julia Lawall <julia@diku.dk>
Error codes are stored in rc, but the return value is always 0. Return rc instead.
The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @r@ local idexpression x; constant C; @@
if (...) { ... x = -C ... when != x ( return <+...x...+>; | return NULL; | return; | * return ...; ) } // </smpl>
Signed-off-by: Julia Lawall <julia@diku.dk>
--- This changes the semantics of the function, but currently its return value is ignored. Alternatively, the function could be converted to return nothing.
