+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.
