Includes the offset from the start of the function if found, otherwise the offset will be added to the module (if found, between brackets)\&. Returns the backtrace as string (each line terminated by a newline character)\&. Note that the returned stack will be truncated to MAXSTRINGLEN, to print fuller and richer stacks use print_ustack\&.
