| * This is the source code for our Coverity user model file. The |
| * purpose of user models is to increase scanning accuracy by explaining |
| * code Coverity can't see (out of tree libraries) or doesn't |
| * sufficiently understand. Better accuracy means both fewer false |
| * positives and more true defects. Memory leaks in particular. |
| * |
| * - 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 |
| * https://scan.coverity.com/projects/54 |
| * |
| * above text is based on https://github.com/qemu/qemu/blob/master/scripts/coverity-model.c |
