Project functions overview
The following table shows data about each function in the project. The functions included in this table correspond 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 |

Fuzzer details
Fuzzer: mruby_fuzzer
Call tree
The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Files and Directories in report
This section shows which files and directories are considered in this report. The main reason for showing this is fuzz introspector may include more code in the reasoning than is desired. This section helps identify if too many files/directories are included, e.g. third party code, which may be irrelevant for the threat model. In the event too much is included, fuzz introspector supports a configuration file that can exclude data from the report. See the following link for more information on how to create a config file: link
