RE: [cdt-dev] How to differenciate a call to a function fromareferencing its address?
|
The AST contains the entire information. In one case you'd be looking at
a function-call expression (IASTFunctionCallExpression), in the other
there would not be one. You can find the function-call by looking at the
parents of the IASTName, which is the reference to the function. The
arguments are then available via
IASTTFunctionCallExpression.getParameterExpression(). This method should
correctly be called getArgumentExpression().
