Detailed Description

Represents an abstract call to a function or method along a particular path.

CallEvents are created through the factory methods of CallEventManager.

CallEvents should always be cheap to create and destroy. In order for CallEventManager to be able to re-use CallEvent-sized memory blocks, subclasses of CallEvent may not add any data members to the base class. Use the "Data" and "Location" fields instead.

◆ isGlobalCFunction()

bool CallEvent::isGlobalCFunction ( StringRef SpecificName = StringRef() ) const

Returns true if the callee is an externally-visible function in the top-level namespace, such as malloc.

You can use this call to determine that a particular function really is a library function and not, say, a C++ member function with the same name.

If a name is provided, the function must additionally match the given name.

Note that this deliberately excludes C++ library functions in the std namespace, but will include C library functions accessed through the std namespace. This also does not check if the function is declared as 'extern "C"', or if it uses C++ name mangling.

This uses the callee decl found by default name lookup rather than the definition because it represents a public interface, and probably has more annotations.
