+
+    Constructs a QLatin1String object that stores \a str.
+
+    The string data is \e not copied. The caller must be able to
+    guarantee that the data which \a str is pointing to will not
+    be deleted or modified as long as the QLatin1String object
+    exists. The size is obtained from \a str as-is, without checking
+    for a null-terminator.
