可以使用Clang AST打印带有名称的函数指针的QualType吗？

#include <iostream>
#include <clang/AST/AST.h>
#include <clang/AST/ASTContext.h>
#include <clang/AST/RecursiveASTVisitor.h>
#include <clang/Frontend/ASTUnit.h>
#include <clang/Tooling/Tooling.h>

using namespace clang;

class FunctionPointerVisitor : public RecursiveASTVisitor<FunctionPointerVisitor> {
public:
    bool VisitFunctionDecl(FunctionDecl* decl) {
        if (decl->getType()->isFunctionPointerType()) {
            QualType qualType = decl->getType();
            std::cout << "Function Pointer QualType: " << qualType.getAsString() << std::endl;
        }
        return true;
    }
};

int main() {
    std::string fileName = "your_file.cpp";
    std::vector<std::string> args = {"-std=c++11"};

    auto astUnit = clang::tooling::buildASTFromCodeWithArgs("", fileName, args);
    if (astUnit) {
        FunctionPointerVisitor visitor;
        visitor.TraverseDecl(astUnit->getASTContext().getTranslationUnitDecl());
    }

    return 0;
}
