Inline stack frames with IDebugControl5.GetContextStackTraceEx?

Question

How can I resolve the symbols of a DEBUG_STACK_FRAME_EX with inline frames?

I am aware of DEBUG_STACK_FRAME_EX and its ULONG InlineFrameContext, but I don't understand how to resolve the InlineFrameContext to the corresponding symbol.

And what is the FrameSignature and FrameId in INLINE_FRAME_CONTEXT?

This is using some wrappers, but the intention should be clear. Using IDebugSymbols4::GetNameByInlineContext if the InlineFrameContext indicates that it is an inline frame, and IDebugSymbols4::GetSymbolNameByOffset otherwise.

C# example below:

ulong displacement;
var builder = new StringBuilder(256);
var isInlineFrame = frame.InlineFrameContext.FrameType.HasFlag(StackFrameType.Inline);
if (isInlineFrame)
{
    _symbols5.GetNameByInlineContext(frame.InstructionOffset, frame.InlineFrameContext.ContextValue, ref builder, out displacement);                
}
else {
    _symbols5.GetSymbolNameByOffset(frame.InstructionOffset, ref builder, out displacement);
}
var name = builder.ToString();
