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

NAME         top

       function::ustack - Return address at given depth of user stack
       backtrace

SYNOPSIS         top

           ustack:long(n:long)

ARGUMENTS         top

       n
           number of levels to descend in the stack.

DESCRIPTION         top

       Performs a simple (user space) 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 ustack is called, or in what
       order.
