DESCRIPTION
sl@0
    41
The <<stdio>> functions maintain an error indicator with each file
sl@0
    42
pointer <[fp]>, to record whether any read or write errors have
sl@0
    43
occurred on the associated file or stream.  Similarly, it maintains an
sl@0
    44
end-of-file indicator to record whether there is no more data in the
sl@0
    45
file.
sl@0
    46
sl@0
    47
Use <<clearerr>> to reset both of these indicators.
sl@0
    48
sl@0
    49
See <<ferror>> and <<feof>> to query the two indicators.
sl@0

    52
RETURNS
sl@0
    53
<<clearerr>> does not return a result.
sl@0
    54
sl@0
    55
PORTABILITY
sl@0
    56
ANSI C requires <<clearerr>>.
sl@0
    57
sl@0
    58
No supporting OS subroutines are required.
