I use it to create a Singleton object, a Signleton is a Design Pattern which allows you to control the creation of a class, an example: (stolen)

    class Singleton{  static Singleton s;  int i;  Singleton(int x) : i(x) { }  void operator=(Singleton&);  Singleton(const Singleton&);public:  static Singleton& getHandle()  {    return s;  }  int getValue() { return i }  void setValue(int x) { i = x }};Singleton Singleton::s(47);int main(){  Singleton& s = Singleton::getHandle();  cout << s.getValue() << endl;  Singleton& s2 = Singleton::getHandle();  s2.setValue(9);  cout << s.getValue() << endl;}    

This example (shamelessly stolen from Bruce Eckel''s Book ''Thinking in C++ 2nd Edition Volume 2) creates a class that can be not be instantiated by the user, the user (read client programmer) can however request a handle from the object. For a better explanation read Bruce Eckels book (follow the link above) it is downloadable in pdf format.

Well, in that case... doesn''t the user (client programmer) still need access to the header file with the class definition? And if so, he/she can still just move the contructor to ''public'' and the whole idea sort of disappears?


Anyway, I''ve never used #pragma directives when programming for Linux, but in MSVC++ you do it like

#pragma warning( disable: 42 763 )

which will disable warning messages 42 and 763.

man gcc

look for the -W switch

"Nazrix is cool" Nazrix first, then Darkmage, then Nazrix again

I already looked there and couldn''t find any argument disabling this specific warning....

Thanks anyway.
