ferror, feof, clearerr, fileno - stream status inquiries
Feof returns non-zero when end of file is read on the named input stream, otherwise zero. Unless cleared by clearerr, the end-of-file
indication lasts until the stream is closed.
Ferror returns non-zero when an error has occurred reading or writing the named stream, otherwise zero. Unless cleared by clearerr, the
error indication lasts until the stream is closed.
Clearerr resets the error and end-of-file indicators on the named stream.
Fileno returns the integer file descriptor associated with the stream, see open(2).
Currently all of these functions are implemented as macros; they cannot be redeclared.

clearerr, feof, ferror, fileno - check and reset stream status
void clearerr(FILE *stream);
int feof(FILE *stream);
int ferror(FILE *stream);
int fileno(FILE *stream);
The function clearerr clears the end-of-file and error indicators for the stream pointed to by stream.
The function feof tests the end-of-file indicator for the stream pointed to by stream, returning non-zero if it is set. The end-of-file
indicator can only be cleared by the function clearerr.
The function ferror tests the error indicator for the stream pointed to by stream, returning non-zero if it is set. The error indicator
can only be reset by the clearerr function.
The function fileno examines the argument stream and returns its integer descriptor.
For non-locking counterparts, see unlocked_stdio(3).
These functions should not fail and do not set the external variable errno. (However, in case fileno detects that its argument is not a
valid stream, it must return -1 and set errno to EBADF.)
The functions clearerr, feof, and ferror conform to X3.159-1989 (``ANSI C'').
