25 FUNCTION |
|
26 <<clearerr>>---clear file or stream error indicator |
|
27 |
|
28 INDEX |
|
29 clearerr |
|
30 |
|
31 ANSI_SYNOPSIS |
|
32 #include <stdio.h> |
|
33 void clearerr(FILE *<[fp]>); |
|
34 |
|
35 TRAD_SYNOPSIS |
|
36 #include <stdio.h> |
|
37 void clearerr(<[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. Similarly, it maintains an |
|
44 end-of-file indicator to record whether there is no more data in the |
|
45 file. |
|
46 |
|
47 Use <<clearerr>> to reset both of these indicators. |
|
48 |
|
49 See <<ferror>> and <<feof>> to query the two indicators. |
|
50 |
|
51 |
|
52 RETURNS |
|
53 <<clearerr>> does not return a result. |
|
54 |
|
55 PORTABILITY |
|
56 ANSI C requires <<clearerr>>. |
|
57 |
|
58 No supporting OS subroutines are required. |
