FUNCTION
<<ferror>>---test whether read/write error has occurred

INDEX
	ferror

ANSI_SYNOPSIS
	#include <stdio.h>
	int ferror(FILE *<[fp]>);

TRAD_SYNOPSIS
	#include <stdio.h>
	int ferror(<[fp]>)
	FILE *<[fp]>;

DESCRIPTION
The <<stdio>> functions maintain an error indicator with each file
pointer <[fp]>, to record whether any read or write errors have
occurred on the associated file or stream.
Use <<ferror>> to query this indicator.

See <<clearerr>> to reset the error indicator.

RETURNS
<<ferror>> returns <<0>> if no errors have occurred; it returns a
nonzero value otherwise.

PORTABILITY
ANSI C requires <<ferror>>.

No supporting OS subroutines are required.
