Functions of interest to fuzz

This section outlines functions that may be of interest to fuzz. They are based on ranking functions that have a lot of complexity but currently exhibit low code coverage. The complexity is calculated based on the function itself as well as the functions called by the given function, i.e. the tree of code that the function triggers.


This is only a minor amount of introspection information available for this project. Please consult the Fuzz Introspector report for more information, e.g. the introspection table of all functions in the target project available here.
