The comments/header of the file are taken from qemu, they provide some basic documentation The code from the examples Ive no means to test this except uploading to coverity for FFmpeg, so each commit should stay simple, making it easy to revert. Also please help making this a useful and effective file by contributing changes/code to it and reviewing contributions. I am happy to upload changes but i cannot really maintain this (alone) as i cannot test changes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

/*
|
|
* 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
|
|
*
