/*
* 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
