C90, like all later standards, supports file operations only in hosted
implementations, not in freestanding implementations.  Even on a
conforming hosted implementation, every call to fopen() could fail.

C90 will never be extended.  It was made obsolete by C99, which was made
obsolete by C11, which was made obsolete by C23.  You're free to invent
your own language based on C90 if you like, but C went in a different
direction decades ago.
