Hello rooters, I have a question about pointer to function. Simple example. #include <stdio.h> int ff(int (*fptr)(const char *txt),const char *txt) { (*fptr)(txt); return 0; } int aaa(const char *txt){ printf(txt); return 0;} root [0] .L ff.C root [1] ff(aaa,"AAAA called\n"); AAAA called root [2] ff(printf,"PPPP called\n"); PPPP called Everything OK. Somehow CINT distinguishes pointer to CINT function (aaa) from pointer to C++ function (printf) and works well. But when ff.C linked to ROOT, then it still works with C++ function (printf) and does not work anymore with CINT function. It is clear, that C++ does not understand pointer to CINT function. Questions: 1. Is it possible to call or execute CINT function from C++ code? By pointer or by name or ... 2. Is it possible by value of pointer to understand does it pointed out to C++ or to CINT function being inside C++ (not CINT) function?
