FUNCTION::PROBEFUNC(3stap)  Context Functions FUNCTION::PROBEFUNC(3stap)

NAME         top

       function::probefunc - Return the probe point's function name, if
       known

SYNOPSIS         top

           probefunc:string()

ARGUMENTS         top

       None

DESCRIPTION         top

       This function returns the name of the function being probed based
       on the current address, as computed by symname(addr) or
       usymname(uaddr) depending on probe context (whether the probe is
       a user probe or a kernel probe).

PLEASE NOTE         top

       this function's behaviour differs between SystemTap 2.0 and
       earlier versions. Prior to 2.0, probefunc obtained the function
       name from the probe point string as returned by pp, and used the
       current address as a fallback.

       Consider using ppfunc instead.
