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

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

SYNOPSIS
	   probefunc:string()

ARGUMENTS
       None

DESCRIPTION
       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
       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.
