Yes. But, as it is implementation dependant, it isn't discussed here.

Nonsense. The standard functions have to accompany the compiler; the compiler
doesn't have to implement them in the same manner that it implements a switch()
or if() statement. I/O functions are /not necessarily/ intrinsic to the compiler
(unlike COBOL or Fortran, where the I/O facilities are parsable language
elements, and not callable functions).
