+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.
