I'm using Xcode/lldb to debug some C code. But I get this error
(lldb) p (int)g_list_position(start, next)
(int) $0 = 1
(lldb) p (int)g_list_position(start, this)
error: expected unqualified-id
error: invalid use of 'this' outside of a non-static member function
So apparently lldb things "this" is a reference to a class, in spite of it being a perfectly valid var in C (and its value is 0, as it should be). Is there some way to escape this name in lldb?
No, the expression evaluator in lldb wraps your expression (at at a source level) with some C++ to pass the arguments in. The only suggestion I can think of is to get the address in the this pointer and put that in the expression explicitly. It's a goal of the expression evaluation that you can copy a line of source in your program and execute it as an expression in lldb .. but this is a corner case where that does not work - variables in C that are reserved words in C++.
