__STDIN__ and __STDOUT__

[noridotjabi@gmail.com]

Before I knew C I think that I remember seeing some C code that had
something to do with __STDIN__ and __STDOUT__ I was wondering if that
is a part of the C language and if so what it is.
Thanks

No, it is not. It is an extension provided by the compiler or some
library used with it.

In C, the identifiers "stdin", "stdout", and "stderr" are macros
defined in <stdio.h> and evaluate to FILE* pointers for the three
pre-opened streams.
