If I have this struct in C:
struct spam {
int ham;
char foo;
};
if I have this declaration:
struct spam s_;
If I wanted to pass a reference to a function of s_'s foo character, I
can do something like this:
somefunc(&s_.foo)
How do I do the same thing in ctypes?
ctypes.addressof(s_) + ctypes.sizeof(spam.foo)*(1)
ctypes.addressof(s_) + spam.foo.offset
Another way: ctypes from Python 2.6 lets you say:
byref(s_, spam.foo.offset)
