sl@0: FUNCTION
sl@0: <<clearerr>>---clear file or stream error indicator
sl@0: 
sl@0: INDEX
sl@0: 	clearerr
sl@0: 
sl@0: ANSI_SYNOPSIS
sl@0: 	#include <stdio.h>
sl@0: 	void clearerr(FILE *<[fp]>);
sl@0: 
sl@0: TRAD_SYNOPSIS
sl@0: 	#include <stdio.h>
sl@0: 	void clearerr(<[fp]>)
sl@0: 	FILE *<[fp]>;
sl@0: 
sl@0: DESCRIPTION
sl@0: The <<stdio>> functions maintain an error indicator with each file
sl@0: pointer <[fp]>, to record whether any read or write errors have
sl@0: occurred on the associated file or stream.  Similarly, it maintains an
sl@0: end-of-file indicator to record whether there is no more data in the
sl@0: file.
sl@0: 
sl@0: Use <<clearerr>> to reset both of these indicators.
sl@0: 
sl@0: See <<ferror>> and <<feof>> to query the two indicators.
sl@0: 
sl@0: 
sl@0: RETURNS
sl@0: <<clearerr>> does not return a result.
sl@0: 
sl@0: PORTABILITY
sl@0: ANSI C requires <<clearerr>>.
sl@0: 
sl@0: No supporting OS subroutines are required.
