`clearerr'--clear file or stream error indicator
void clearerr(FILE *FP);
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.
`clearerr' does not return a result.
ANSI C requires `clearerr'.
No supporting OS subroutines are required.
