NAME         top

       function::print_ubacktrace - Print stack back trace for current
       user-space task.

SYNOPSIS         top

       1) print_ubacktrace()

       2) print_ubacktrace(pc:long,sp:long,fp:long)

ARGUMENTS         top

       pc
           override PC

       sp
           override SP

       fp
           override FP

DESCRIPTION         top

       1)

       2) Equivalent to print_ustack(ubacktrace), except that deeper
       stack nesting may be supported. Returns nothing. See
       print_backtrace for kernel backtrace.

       Equivalent to print_ubacktrace, but it performs the backtrace
       using the pc, sp, and fp provided. Useful

NOTE         top

       To get (full) backtraces for user space applications and shared
       shared libraries not mentioned in the current script run stap
       with -d /path/to/exe-or-so and/or add --ldd to load all needed
       unwind data.
