FUNCTION::STACK(3stap) Context Functions FUNCTION::STACK(3stap)

NAME
       function::stack - Return address at given depth of kernel stack
       backtrace

SYNOPSIS
           stack:long(n:long)

ARGUMENTS
       n
           number of levels to descend in the stack.

DESCRIPTION
       Performs a simple (kernel) backtrace, and returns the element at the
       specified position. The results of the backtrace itself are cached, so
       that the backtrace computation is performed at most once no matter how
       many times stack is called, or in what order.
