/*
|
|
* 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
|
