Chapter 29 Pragmas for C++

// the static local variable will be constructed only once.

static std::string localstring = thread_unsafe_func();

}

NOTE

When an exception is thrown from a static local initializer, the initializer is retried by the next client that enters the scope of the local.

This pragma does not correspond to any panel setting. By default, this pragma is off

.

29.43 warn_hidevirtual

Controls the recognition of a non-virtual member function that hides a virtual function in a superclass.

Syntax

#pragma warn_hidevirtual on | off | reset

Remarks

If you enable this pragma, the compiler issues a warning message if you declare a nonvirtual member function that hides a virtual function in a superclass. One function hides another if it has the same name but a different argument type.

Listing 29-14 on page 465

shows an example.

Listing 29-14. Hidden Virtual Functions

class A {

public:

virtual void f(int);

virtual void g(int);

}; class B: public A {

public:

void f(char); // WARNING: Hides A::f(int)

virtual void g(int); // OK: Overrides A::g(int)

};

The ISO/IEC 14882:2003 C++ Standard does not require this pragma.

NOTE

A warning message normally indicates that the pragma name is not recognized, but an error indicates either a syntax problem or that the pragma is not valid in the given context.
