Project functions overview
The following table shows data about each function in the project. The functions included in this table corresponds to all functions that exist in the executables of the fuzzers. As such, there may be functions that are from third-party libraries.
For further technical details on the meaning of columns in the below table, please see the Glossary .
| Func name | Functions filename | Args | Function call depth | Reached by Fuzzers | Fuzzers runtime hit | Func lines hit % | I Count | BB Count | Cyclomatic complexity | Functions reached | Reached by functions | Accumulated cyclomatic complexity | Undiscovered complexity |

Call tree overview
The following is the call tree with color coding for which functions are hit/not hit. This info is based on the coverage achieved of all fuzzers together and not just this specific fuzzer. This should change in the future to be per-fuzzer-basis.
For further technical details on what the call tree overview is, please see the Glossary .
