bool hasVoidPointerToNonConstArg () const Returns true if any of the arguments is void*.
virtual bool argumentsMayEscape () const Returns true if any of the arguments are known to escape to long- term storage, even if this method will not modify them.
bool isGlobalCFunction (StringRef SpecificName=StringRef()) const Returns true if the callee is an externally-visible function in the top-level namespace, such as malloc.

const ParamVarRegion * getParameterLocation (unsigned Index, unsigned BlockCount) const Returns memory location for a parameter variable within the callee stack frame.
bool isArgumentConstructedDirectly (unsigned Index) const Returns true if on the current path, the argument was constructed by calling a C++ constructor over it.
virtual std::optional< unsigned > getAdjustedParameterIndex (unsigned ASTArgumentIndex) const Some calls have parameter numbering mismatched from argument numbering.
virtual unsigned getASTArgumentIndex (unsigned CallArgumentIndex) const Some call event sub-classes conveniently adjust mismatching AST indices to match parameter indices.
const ConstructionContext * getConstructionContext () const Returns the construction context of the call, if it is a C++ constructor call or a call of a function returning a C++ class instance.
std::optional< SVal > getReturnValueUnderConstruction () const If the call returns a C++ record type then the region of its return value can be retrieved from its construction context.
