Hooking getchar() is very easy, but how to how to hook std::cin?

Here is the method to hook getchar(): Using a shared library which has a function named getchar(i.e int getchar(void){printf("test\n");}).Then start the target program with PRE_LOAD_PATH macro.

Could anybody shed some light on this question? It would be better if you could give a simple implementation.
