    25 FUNCTION

    26 <<ferror>>---test whether read/write error has occurred

    27 

    28 INDEX

    29 	ferror

    30 

    31 ANSI_SYNOPSIS

    32 	#include <stdio.h>

    33 	int ferror(FILE *<[fp]>);

    34 

    35 TRAD_SYNOPSIS

    36 	#include <stdio.h>

    37 	int ferror(<[fp]>)

    38 	FILE *<[fp]>;

    39 

    40 DESCRIPTION

    41 The <<stdio>> functions maintain an error indicator with each file

    42 pointer <[fp]>, to record whether any read or write errors have

    43 occurred on the associated file or stream.

    44 Use <<ferror>> to query this indicator.

    45 

    46 See <<clearerr>> to reset the error indicator.

    47 

    48 RETURNS

    49 <<ferror>> returns <<0>> if no errors have occurred; it returns a

    50 nonzero value otherwise.

    51 

    52 PORTABILITY

    53 ANSI C requires <<ferror>>.

    54 

    55 No supporting OS subroutines are required.
