usym Action
            
         _usymaddr usym(uintptr_t address)
The usym action translates the specified address according to the setting of the uresolve option.
               
By default, usym formats an address as a symbol. For example, if uaddr produces the following format:
               
date`clock_val+0x1
then the usym action would produce the following format:
               
date`clock_val
The behavior of the usym action can be modified by using the uresolve option. For more information, see DTrace User Address Symbol Resolution.
