13 * This is the source code for our Coverity user model file. The
14 * purpose of user models is to increase scanning accuracy by explaining
15 * code Coverity can't see (out of tree libraries) or doesn't
16 * sufficiently understand. Better accuracy means both fewer false
17 * positives and more true defects. Memory leaks in particular.

19 * - A model file can't import any header files. Some built-in primitives are
20 * available but not wchar_t, NULL etc.
21 * - Modeling doesn't need full structs and typedefs. Rudimentary structs
22 * and similar types are sufficient.
23 * - An uninitialized local variable signifies that the variable could be
24 * any value.
25 *
26 * The model file must be uploaded by an admin in the analysis settings of
27 * https://scan.coverity.com/projects/54
