Nreturn 1.0

Nreturn 1.0 is considered as a useful and easy to use utility to detect functions in C Source code that have multiple exit paths. These are functions which create maintenance risk for the project where minor modifications need disproportionate verification effort.

Nreturn could also be used to list C functions that have too many while loops in them. Such a list when reviewed could expose nested while loops in the project. Invoking functions in nested while loops is often considered a risk to meeting Execution deadlines like petting Watchdog and scheduling latencies in Non-premptive systems.
