Upon successful completion, fileno() shall return the integer value of
the file descriptor associated with stream. Otherwise, the value -1 shall be
returned and errno set to indicate the error.
The fileno() function may fail if:
The stream argument is not a valid stream, or the stream is not
associated with a file.
