clearerr, feof, ferror, fileno − check and reset stream status
#include <stdio.h>
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 C89.
