Hi,
I came across the formatter example in unicode_strings.py where in
utf16_summary() I see this code:
string_data = value.process.ReadMemory(pointer, length, error)
# utf8 is safe to emit as-is on OSX
return '"%s"' % (string_data.decode('utf-16').encode('utf-8'))
I am trying to replicate that in my own formatter and I'm having difficulty
converting the pointer to an addr_t which is what ReadMemory wants. In my
case pointer comes from:
self.rep.GetChildMemberWithName("__l").GetChildMemberWithName("__data_")
(this is a basic_string which has a union:
struct __rep
{
union {
__long __l; // Used for long strings
__short __s; // Used for short strings - stores in place
__raw __r; // ??
};
};
and __long is defined as:
struct __long {
pointer __data_;
size_type __size_;
size_type __cap_;
};
So __data_ is a basic_string::pointer (plain C pointer).
How do I convert this pointer to the addr_t that I need? I believe that the
GetChildMemberWithName returns an SBValue. I tried pointer.GetPointeeData(0,
1).GetLoadAddress() but I'm not getting the corect results.
Thanks!
Florin
