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

NAME

       function::addr - Address of the current probe point.

SYNOPSIS

	   addr:long()

ARGUMENTS

       None

DESCRIPTION

       Returns the instruction pointer from the current probe's register state. Not all probe types have registers though, in which case zero is
       returned. The returned address is suitable for use with functions like symname and symdata.
