 This class defines an interface to the CINT C/C++ interpreter made   
 by Masaharu Goto from HP Japan.                                      
                                                                      
 CINT is an almost full ANSI compliant C/C++ interpreter.

 Initialize all registered dictionaries. Normally this is already done
 by G__init_cint() and G__dlmod().
void EnableAutoLoading()
 Enable the automatic loading of shared libraries when a class
 is used that is stored in a not yet loaded library. Uses the
 information stored in the class/library map (typically
 $ROOTSYS/etc/system.rootmap).
void EndOfLineAction()
 It calls a "fantom" method to synchronize user keyboard input
 and ROOT prompt line.
Bool_t IsLoaded(const char* filename)
 Return true if the file has already been loaded by cint.

void LoadMacro(const char *filename, EErrorCode *error)
 Load a macro file in CINT's memory.
Long_t ProcessLine(const char *line, EErrorCode *error)
 Let CINT process a command line.
 If the command is executed and the result of G__process_cmd is 0,
 the return value is the int value corresponding to the result of the command
 (float and double return values will be truncated).
Long_t ProcessLineAsynch(const char *line, EErrorCode *error)
 Let CINT process a command line asynch.
Long_t ProcessLineSynch(const char *line, EErrorCode *error)
 Let CINT process a command line synchronously, i.e we are waiting
 it will be finished.
Long_t Calc(const char *line, EErrorCode *error)
 Directly execute an executable statement (e.g. "func()", "3+5", etc.
 however not declarations, like "Int_t x;").
void PrintIntro()
 Print CINT introduction and help message.
void RecursiveRemove(TObject *obj)
 Delete object from CINT symbol table so it can not be used anymore.
 CINT object are always on the heap.
void Reset()
 Reset the CINT state to the state saved by the last call to
 TCint::SaveContext().
void ResetAll()
 Reset the CINT state to its initial state.
void ResetGlobals()
 Reset the CINT global object state to the state saved by the last
 call to TCint::SaveGlobalsContext().
void RewindDictionary()

 the current macro. This function is typically called after SEGV or
 ctlr-C after doing a longjmp back to the prompt.
Int_t DeleteGlobal(void *obj)
 Delete obj from CINT symbol table so it cannot be accessed anymore.
 Returns 1 in case of success and 0 in case object was not in table.
void SaveContext()
 Save the current CINT state.

TString GetMangledName(TClass *cl, const char *method, const char *params)
 Return the CINT mangled name for a method of a class with parameters
 params (params is a string of actual arguments, not formal ones). If the
 class is 0 the global function list will be searched.
TString GetMangledNameWithPrototype(TClass *cl, const char *method, const char *proto)
 Return the CINT mangled name for a method of a class with a certain
 prototype, i.e. "char*,int,float". If the class is 0 the global function
 list will be searched.
void * GetInterfaceMethod(TClass *cl, const char *method, const char *params)
 Return pointer to CINT interface function for a method of a class with
 parameters params (params is a string of actual arguments, not formal
 ones). If the class is 0 the global function list will be searched.
void * GetInterfaceMethodWithPrototype(TClass *cl, const char *method, const char *proto)
 Return pointer to CINT interface function for a method of a class with
 a certain prototype, i.e. "char*,int,float". If the class is 0 the global
 function list will be searched.
const char * GetInterpreterTypeName(const char *name, Bool_t full)
 The 'name' is known to the interpreter, this function returns
 the internal version of this name (usually just resolving typedefs)
 This is used in particular to synchronize between the name used
 by rootcint and by the run-time enviroment (TClass)
 Return 0 if the name is not known.
void Execute(const char *function, const char *params, int *error)
 Execute a global function with arguments params.
void Execute(TObject *obj, TClass *cl, const char *method, const char *params, int *error)

 (params[0] ... params[n] = array of TObjString parameters).
Long_t ExecuteMacro(const char *filename, EErrorCode *error)
 Execute a CINT macro.
const char * GetTopLevelMacroName()
 Return the file name of the current un-included interpreted file.
 See the documentation for GetCurrentMacroName().
const char * GetCurrentMacroName()
 Return the file name of the currently interpreted file,
 included or not. Example to illustrate the difference between
 GetCurrentMacroName() and GetTopLevelMacroName():
 
inclfile.h
#include <iostream>
void inclfunc() {
   std::cout << "In inclfile.h" << std::endl;
   std::cout << "  TCint::GetCurrentMacroName() returns  " <<
      TCint::GetCurrentMacroName() << std::endl;
   std::cout << "  TCint::GetTopLevelMacroName() returns " <<
      TCint::GetTopLevelMacroName() << std::endl;
}
mymacro.C
#include <iostream>
#include "inclfile.h"
void mymacro() {
   std::cout << "In mymacro.C" << std::endl;
   std::cout << "  TCint::GetCurrentMacroName() returns  " <<
      TCint::GetCurrentMacroName() << std::endl;
   std::cout << "  TCint::GetTopLevelMacroName() returns " <<
      TCint::GetTopLevelMacroName() << std::endl;
   std::cout << "  Now calling inclfunc..." << std::endl;
   inclfunc();
}
 Running mymacro.C will print:

 root [0] .x mymacro.C
 In mymacro.C
   TCint::GetCurrentMacroName() returns  ./mymacro.C
   TCint::GetTopLevelMacroName() returns ./mymacro.C
   Now calling inclfunc...
 In inclfile.h
   TCint::GetCurrentMacroName() returns  inclfile.h
   TCint::GetTopLevelMacroName() returns ./mymacro.C
const char * TypeName(const char *typeDesc)
 Return the absolute type of typeDesc.
 E.g.: typeDesc = "class TNamed**", returns "TNamed".
 You need to use the result immediately before it is being overwritten.
Int_t LoadLibraryMap()
 Load map between class and library. Cint uses this information to
 automatically load the shared library for a class (autoload mechanism).
 See also the AutoLoadCallback() method below.
Int_t AutoLoad(const char *cls)
 Load library containing specified class. Returns 0 in case of error
 and 1 in case if success.
Int_t AutoLoadCallback(const char *cls, const char *lib)
 Load library containing specified class. Returns 0 in case of error
 and 1 in case if success.
void * FindSpecialObject(const char *item, G__ClassInfo *type, void **prevObj, void **assocPtr)
 Static function called by CINT when it finds an un-indentified object.
 This function tries to find the UO in the ROOT files, directories, etc.
 This functions has been registered by the TCint ctor.
void UpdateClassInfo(char *item, Long_t tagnum)
 Static function called by CINT when it changes the tagnum for
 a class (e.g. after re-executing the setup function). In such
 cases we have to update the tagnum in the G__ClassInfo used by
 the TClass for class "item".
void UpdateAllCanvases()
 Update all canvases at end the terminal input command.
const char* GetSharedLibs()
 Refresh the list of shared libraries and return it.
const char * GetClassSharedLibs(const char *cls)
 Get the list of shared libraries containing the code for class cls.
 The first library in the list is the one containing the class, the
 others are the libraries the first one depends on. Returns 0
 in case the library is not found.
const char * GetSharedLibDeps(const char *lib)
 Get the list a libraries on which the specified lib depends. The
 returned string contains as first element the lib itself.
 Returns 0 in case the lib does not exist or does not have
 any dependencies.
Bool_t IsErrorMessagesEnabled()
 If error messages are disabled, the interpreter should suppress its
 failures and warning messages from stdout.
Bool_t SetErrorMessages(Bool_t enable)
 If error messages are disabled, the interpreter should suppress its
 failures and warning messages from stdout. Return the previous state.
void AddIncludePath(const char *path)
 Add the given path to the list of directories in which the interpreter
 looks for include files. Only one path item can be specified at a
 time, i.e. "path1:path2" is not supported.
const char * GetIncludePath()
 Refresh the list of include paths known to the interpreter and return it
 with -I prepended.
