checking if object is member of

[pavol]

Hi to all. I have a function that takes an ostream object as an argument. I want to be able to pass to it either cout or a file stream. Is there any way I can distinguish between the two. For example:

code:

ostream &out if(out is a member of ofstream)     //do file stuff else     //do terminal stuff

Passing an additional flag is probably the easiest way, otherwise...


Well... you could use typeid() (see: http://www.cplusplus.com/doc/tutorial/typecasting.html). But really, why do you want to do something different? It's an output stream... just output whatever.

code:

<some_type> foo(std::ostream& out) { ... } <some_type> foo(std::ofstream& out) { ... }
