FUNCTION::PROBEFUNC(3stap)  Context FunctionsFUNCTION::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,probefuncobtained the function       name from the probe point string as returned bypp, and used the       current address as a fallback.       Consider usingppfuncinstead.
