14/** \class TClingCallFunc
15Emulation of the CINT CallFunc class.
16
17The CINT C++ interpreter provides an interface for calling
18functions through the generated wrappers in dictionaries with
19the CallFunc class. This class provides the same functionality,
20using an interface as close as possible to CallFunc but the
21function metadata and calling service comes from the Cling
22C++ interpreter and the Clang C++ compiler, not CINT.
