sl@0: FUNCTION
sl@0: <<ferror>>---test whether read/write error has occurred
sl@0: 
sl@0: INDEX
sl@0: 	ferror
sl@0: 
sl@0: ANSI_SYNOPSIS
sl@0: 	#include <stdio.h>
sl@0: 	int ferror(FILE *<[fp]>);
sl@0: 
sl@0: TRAD_SYNOPSIS
sl@0: 	#include <stdio.h>
sl@0: 	int ferror(<[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.
sl@0: Use <<ferror>> to query this indicator.
sl@0: 
sl@0: See <<clearerr>> to reset the error indicator.
sl@0: 
sl@0: RETURNS
sl@0: <<ferror>> returns <<0>> if no errors have occurred; it returns a
sl@0: nonzero value otherwise.
sl@0: 
sl@0: PORTABILITY
sl@0: ANSI C requires <<ferror>>.
sl@0: 
sl@0: No supporting OS subroutines are required.
