dbg:frame-next-nth-interesting-active-frame frame &optional Function
(count 1)
dbg:frame-next-nth-interesting-active-frame goes up the stack by count interesting
active frames from frame and returns a frame pointer to that
frame. It returns a second value that is not nil. When count is positive,
this is like calling dbg:frame-next-interesting-active-frame count times;
count can also be negative or zero. If either end of the stack is reached, it
returns a frame pointer to the first or last active frame and nil.
"Next" means the frame of a procedure that was invoked more recently
(the frame called by this one; toward the top of the stack).
"Interesting active frames" include all of the active frames except those
that are parts of the internals of the Lisp interpreter, such as the frames
for eval, apply, funcall, let, and other basic Lisp special forms. The list
of such functions is the value of the system constant,
dbg:*uninteresting-functions* .
Caution: Use this function only within the context of the
dbg:with-erring-frame macro.

dbg:frame-next-nth-open-frame frame &optional (count 1) Function
dbg:frame-next-nth-open-frame goes up the stack by count open frames
from frame and returns a frame pointer to that frame. It returns a second
value that is not nil. When count is positive, this is like calling
dbg:frame-next-open-frame count times; count can also be negative or
zero. If either end of the stack is reached, it returns a frame pointer to
the iust or last active frame and nil.
"Next" means the frame of a procedure that was invoked more recently
(the frame called by this one; toward the top of the stack).
Caution: Use this function only within the context of the
dbg:with-erring-frame macro.

I
dbg:frame-next-open-frame frame Function
dbg:frame-next-open-frame returns a frame pointer to the next open frame
following frame-pointer. If frame is the last open frame on the stack, it
returns nil.
