DESCRIPTION        top

        Context functions provide additional information about where an       event occurred. These functions can provide information such as a       backtrace to where the event occurred and the current register       values for the processor.print_regs              Print a register dump              Seefunction::print_regs(3stap)               for details.ppReturns the active probe point              Seefunction::pp(3stap)               for details.ppfuncReturns the function name parsed from pp()              Seefunction::ppfunc(3stap)               for details.probe_type              The low level probe handler type of the current probe.
