This macro will return the current fixed offset, a compile-time constant expression. This is
always possible when defining a fixed size parser.
- Even in dynamically sized parsers this macro will work, up tp now only fixed size fields have
- been defined. This macro does \e not validate this condition, it will return an arbitrary
- incorrect value otherwise.
+ Even in dynamically sized parsers this macro will work, if all parser defined \e before the
+ current position are fixed-size parsers. This macro does \e not validate this condition, it will
+ return an arbitrary incorrect value otherwise.
