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

NAME         top

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

SYNOPSIS         top

           stack:long(n:long)

ARGUMENTS         top

       n
           number of levels to descend in the stack.

DESCRIPTION         top

       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.
