This takes care of name mangling. So what you are trying to do will not work in a standards compliant C++ compiler. share|improve this answer edited Nov 26 '09 at 8:06 answered Nov 26 '09 at 7:28 Vijay Mathew 19.6k14183 If you could do this, C++ would have something like [closures][1].

file I have this: void (*ptr)(unsigned char*, int, int); void func01(unsigned char*, int, int); And in the http://www.cplusplus.com/forum/general/102086/ implementation file I have this: ptr=&func01; OR C::ptr=&C::func01; etc. Still get errors And this is the error I get: error C2440: '=' : cannot convert from 'void (__thiscall https://answers.yahoo.com/question/index?qid=20090129054709AAA8VW7 C::* )(unsigned char *,int,int)' to 'void (__cdecl *)(unsigned char *,int,int)' 1> There is no context in which this conversion is possible error C2276: '&' : illegal operation on member function bound member function expression If I use: ptr=func01; I get: error C3867: 'C::func01': function call missing argument list; use '&C::func01' to create a pointer to member error C2440: '=' : cannot convert from 'void (__thiscall C::* )(unsigned char *,int,int)' to 'void (__cdecl *)(unsigned char *,int,int)' 1> There is no context in which this conversion is possible SO, '*' illegal operation if I go ptr=&C::func01; I get this: error C2440: '=' : cannot convert from 'void (__thiscall C::* )(unsigned char *,int,int)' to 'void (__cdecl *)(unsigned char *,int,int)' 1> There is no context in which this conversion is possible OR ptr=&func01; I get: error C2276: '&' : illegal operation on bound member function expression Somewhere I'm making some kind of trivial yet fundamental mistake but I can't figure it out and any help is appreciated.

May 14, 2013 at 2:15pm UTC RonInNewYork (4) void func01(unsigned char*, int, int); ONE THING I FORGOT TO MENTION: func01 is a member function (in class C). And the function pointer is also a member of class C. RON May 14, 2013 at 2:17pm UTC Bourgond Aries (415) Please use code tags. I believe the correct syntax is for member functions is: return_type (ClassName::* pointer_name)(input...); And thus becomes: 1
