-# returning-data-from-temporary
-
-Warns when returning the data from a `QByteArray` that will soon be destroyed.
-
-## Examples
-```
-QByteArray b = ...;
-return b.data();
-```
-```
-return funcReturningByteArray().data();
-return funcReturningByteArray().constData();
-```
-
-
-```
-const char * getFoo()
-{
-    QByteArray b = ...;
-    return b; // QByteArray can implicitly cast to char*
-}
-```
-
-```
-    const char *c1 = getByteArray();
-    const char *c2 = str.toUtf8().data();
-```
-
-Note that in some cases it might be fine, since the method can return the data
-of a global static QByteArray. However such code is brittle, it could start crashing
-if it ceased to be static.
