FERROR(3S) — Silicon Graphics

NAME

ferror, feof, clearerr, fileno − stream status inquiries

#include <stdio.h>

int feof (stream) FILE ∗stream;

int ferror (stream) FILE ∗stream;

void clearerr (stream) FILE ∗stream;

int fileno(stream) FILE ∗stream;

Feof returns non-zero when EOF has previously been detected reading the named input stream, otherwise zero.

Ferror returns non-zero when an I/O error has previously occurred reading from or writing to the named stream, otherwise zero.

Clearerr resets the error indicator and EOF indicator to zero on the named stream.

Fileno returns the integer file descriptor associated with the named stream; see open(2).

All these functions are implemented as macros; they cannot be declared or redeclared.
