* libc/stdio/clearerr.c (clearerr): Ensure CHECK_INIT() is
called before _flockfile to prevent lock object use before
initialisation. _REENT_SMALL_CHECK_INIT() and CHECK_INIT()
take a struct _reent * instead of a FILE *.

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.
