NAME         top

       function::sprint_usyms - Return stack for user addresses from
       string

SYNOPSIS         top

           sprint_usyms(callers:string)

ARGUMENTS         top

       callers
           String with list of hexadecimal (user) addresses

DESCRIPTION         top

       Perform a symbolic lookup of the addresses in the given string,
       which are assumed to be the result of a prior calls to ustack,
       ucallers, and similar functions.

       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), as obtained
       from usymdata. 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_usyms.
