FERROR(3) BSD Programmer's Manual FERROR(3)
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 point- ed to by stream, returning non-zero if it is set. The end-of-file indica- tor 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 in- teger file descriptor.
These functions should not fail and do not set the external variable errno.
The functions clearerr(), feof(), and ferror() conform to ANSI X3.159- 1989 ("ANSI C"). The function fileno() conforms to IEEE Std 1003.1-1990 ("POSIX"). MirOS BSD #10-current April 19, 1994 1
