function::print_ubacktrace - Print stack back trace for current user-space task.
Equivalent to print_ustack(ubacktrace), except that deeper stack nesting may be supported. Returns nothing. See print_backtrace for kernel backtrace.
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.
