clearerr---clear file or stream error indicatorSynopsis
#include <stdio.h> void clearerr(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.
