[PATCH v3 17/44] qapi: Use returned bool to check for failure, Coccinelle part |
|
Date: |
Mon, 6 Jul 2020 10:09:23 +0200 |
The previous commit enables conversion of
visit_foo(..., &err);
if (err) {
...
}
to
if (!visit_foo(..., errp)) {
...
}
for visitor functions that now return true / false on success / error.
