[cfe-dev] Traversing a function body for call expressions. How ?

[Gabor Kozar]

Hi,

It should work. Define an StmtVisitor subclass, provide a VisitCallExpr.
Then in your Visitor::VisitFunctionDecl, construct an StmtVisitor
object, then call its Visit method with the function's body.

In the future, please also provide source code, to allow us to spot any
bugs and problems in your code (e.g. you may believe that the code does
what you say it does, but you might have a bug, etc.).

Best regards,
