Not sure what you are asking here. The immediate adds to the current value, where as the indirect will then look what's at that location. If the arg (val) is 0xffffffffabcd0000 u64 val+8 Will return: 0xffffffffabcd0008 u64 val[1] will return what's at location 0xffffffffabcd0008 "u64 val+8[0]" is the same as "u64 val[1]" Note: "u64 val[0]+8" will return what's at location 0xffffffffabcd0000 plus 8. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
