+FUNCTION
+<<clearerr>>---clear file or stream error indicator
+
+INDEX
+	clearerr
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	void clearerr(FILE *<[fp]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	void clearerr(<[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.  Similarly, it maintains an
+end-of-file indicator to record whether there is no more data in the
+file.
+
+Use <<clearerr>> to reset both of these indicators.
+
+See <<ferror>> and <<feof>> to query the two indicators.
+
+
+RETURNS
+<<clearerr>> does not return a result.
+
+PORTABILITY
+ANSI C requires <<clearerr>>.
+
+No supporting OS subroutines are required.
