Detailed Description

OffsetOfExpr - [C99 7.17] - This represents an expression of the form offsetof(record-type, member-designator). For example, given:

 struct S {
   float f;
   double d;
 };
 struct T {
   int i;
   struct S s[10];
 };

we can represent and evaluate the expression offsetof(struct T, s[2].d).

getOperatorLoc - Return the location of the operator.

Return the location of the right parentheses.

SourceRange clang::OffsetOfExpr::getSourceRange

(

)

const [inline]

SourceLocation tokens are not useful in isolation - they are low level value objects created/interpreted by SourceManager. We assume AST clients will have a pointer to the respective SourceManager.
