How to use templates in LabWindows as we use in C++

[vava]

Hello,         Can we use templates in LabWindows CVI as we use in C++.i.e., if we define class with template we can pass variables of any datatype to it or if we define a function with template datatype as argument  then it will accept variable with any datatypes.Hence  there is no need to write same function more than once only becoz its argument's datatype differ.  Expecting Reply, Rgds,    Mala

Hi Mala,

LabWindows/CVI is pure ANSI C and so it doesn't understand any C++ concepts. Check out this forum post which discusses what options you have of mixing CVI with C++.

Best Regards,

Without mixing with C++, you can do a 'dirty' template by using a #define in
some cases. For instance:

#define NUM int
//#define NUM float

NUM FunctionAdd(NUM a, NUM b) {
return a+b;
}

But this method cracks down fairly quickly...

Vava -

Templates in C++ provide static parametric polymorphism

They are similar to generics in Ada.  Java and C# implement generics also. 

But not C89 that we have in CVI.  Or C99 either, as best as I can tell.

You can use C# and C++ with CVI as noted, but I don't think there's any way to use Java or Ada.
