CodeQL library for C/C++

Module SideEffect

Provides an abstract class for accurate dataflow modeling of library functions when source code is not available. To use this QL library, create a QL class extending SideEffectFunction with a characteristic predicate that selects the function or set of functions you are modeling. Within that class, override the predicates provided by SideEffectFunction to match the flow within that function.
