cout implementation

[candy_init@yahoo.com]

hi all,

Is it true that the cout function used in C++ for printing data
to the console is implemented via the "write" system call?
If not then how the cout function is implemented?

Thanks,
Candice

Maybe, or maybe not. That depens on the compiler/OS/library/...
Some OSs don't even have a "write" system call.

The C++ standard doesn't define that. It's up to the implemenation to decide
where the output of cout goes.
