Ensures that frames up to (and including) end_idx are realized in the StackFrameList.

end_idx can be larger than the actual number of frames, in which case all the frames will be fetched. Acquires the writer end of the list mutex. Returns true if the function was interrupted, false otherwise. Callers should first check (under the shared mutex) whether we need to fetch frames or not.

◆ GetNumFrames()

uint32_t StackFrameList::GetNumFrames ( bool can_create = true )

Get the number of visible frames.

Frames may be created if can_create is true. Synthetic (inline) frames expanded from the concrete frame #0 (aka invisible frames) are not included in this count.

◆ GetSelectedFrameIndex()

Get the currently selected frame index.

We should only call SelectMostRelevantFrame if (a) the user hasn't already selected a frame, and (b) if this really is a user facing "GetSelectedFrame". SMRF runs the frame recognizers which can do arbitrary work that ends up being dangerous to do internally. Also, for most internal uses we don't actually want the frame changed by the SMRF logic. So unless this is in a command or SB API, you should pass false here.
