class OffsetOfExpr

Declaration

class OffsetOfExpr : public Expr, private TrailingObjects { /* full declaration omitted */ };

Description

OffsetOfExpr - [C99 7.17] - This represents an expression of the form offsetof(record-type, member-designator). For example, given: we can represent and evaluate the expression @c offsetof(struct T, s[2].d).
