FUNCTION::SPRINT_UST(3stap) Context FunctionsFUNCTION::SPRINT_UST(3stap)

NAME         top

       function::sprint_ustack - Return stack for the current task from
       string.

SYNOPSIS         top

           sprint_ustack:string(stk:string)

ARGUMENTS         top

       stk
           String with list of hexadecimal addresses for the current
           task.

DESCRIPTION         top

       Perform a symbolic lookup of the addresses in the given string,
       which is assumed to be the result of a prior call to ubacktrace
       for the current task.

       Returns a simple backtrace from the given hex string. One line
       per address. Includes the symbol name (or hex address if symbol
       couldn't be resolved) and module name (if found). 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.

NOTE         top

       it is recommended to use sprint_usyms instead of this function.
