Is it ever possible to get the current (member) function name in C++?

If given a function int func(args)in C or C++ is there a way to get the name, or even signature, of the function fromwith in the body of func

I would like to be able to do something like this:

void func(void) 
{
    printf("%s", funcinfo.sig);
}

and have the output be:

"void func(void)"

does anyone know of a way to do this?

Answer 1

There is __PRETTY_FUNCTION__ predefined identifier with gcc:

void func(void) 
{
    printf("%s\n", __PRETTY_FUNCTION__);
}

it will print :

void func()

with gcc in C++

and

func

with gcc in C

Note that this identifier is a gcc extension. In Standard C, there is the predefined identifier __func__ but which prints only the function name (C or C++)
