-/* Coverity Scan model
- * This is a modeling file for Coverity Scan. Modeling helps to avoid false
- * positives.
- *
- * - A model file can't import any header files.  Some built-in primitives are
- *   available but not wchar_t, NULL etc.
- * - Modeling doesn't need full structs and typedefs. Rudimentary structs
- *   and similar types are sufficient.
- * - An uninitialized local variable signifies that the variable could be
- *   any value.
- *
- * The model file must be uploaded by an admin in the analysis settings of
- * http://scan.coverity.com/projects/1919
