It appears that VA X is not able to handle cv-qualified member function pointers as function parameters
struct S { };
void foo(void (S::*func)()); // #1
void foo(void (S::*func)() const); // #2
In #1, all is fine. In #2 however, it doesn't recognize the func parameter - it appears with a red error underline (also inside the function body). This is the case with every cv combination (const, volatile and const volatile) |

I am not seeing any underlining using VS2005 and VA 1540
Can you try changing the color VA uses to underline mistyped symbols, just to be sure that VA is doing the underlining.
Do you see the problem with this test code? |

| Right. If you comment out #1 then you see the error. #1 actually makes #2 work correctly :) |

| There are some coloring issues as well, by the way. It seems that if you define a function pointer variable (any function pointer, so also pointers like void(*func)()), it colors like a function. But if you define a function parameter in such a way, it colors like a variable. |

I am seeing the same thing with the underlining. That was rather unexpected.

The coloring, do you mean something like this?
class felinePtr
{
public:
void (*ptrFn)(int, int);
void ptrParam(void (*func)());
};
It is a long time since I stored function pointers in a structure  |

Yeah. In your example, "ptrFn" will be colored like a function, while "func" will be colored like a variable
It's arguable which one would be correct. They are obviously variables, but you can use them as functions as well. I myself am leaning toward "they're variables", but I can live with it if they were to be colored like functions. Maybe make it a VA X setting? |

I have put in a bug, saying that both should be coloured as variables. Adding an option for this is definitely overkill

I have exactly the same situation, but only in my case VAX does not recognize 'func' from the OP at all. Also only when the const keyword is set.
VAX 1549, VS2005.

What code are you using? I have just tried:
class felinePtr
{
public:
void (*ptrFn)(int, int);
void ptrParam(void (*func1)());
void ptrParam(void (*func2)() const);
};
using VS2003 and VA 1549, and while "func2" is underlined as a mistyped symbol, this line does not compile. |

of cause it doesn't:) only member function [pointers] can have modifiers
class felinePtr
{
public:
void (*ptrFn)(int, int);
void ptrParam(void (*func1)());
// change this
// void ptrParam(void (*func2)() const);
// to
void ptrParam(void (felinePtr::*func2)() const);
};

Seeing your modified version, I remember seeing something similar in another thread recently:
http://forum.wholetomato.com/forum/topic.asp?TOPIC_ID=5991
On reflection I am fairly happy I don't know how to do this off hand, I have seen some deeply suspicious things done in C with function pointers *shudders at the memory*
case=5433
bugfix thank you for your help with this |

1539: ptr to cv-qualified mem func errors
