| 27 | ANSI_SYNOPSIS |
||
| 28 | #include |
||
| 29 | int remove(char *<[filename]>); |
||
| 30 | |||
| 31 | int _remove_r(struct _reent *<[reent]>, char *<[filename]>); |
||
| 32 | |||
| 33 | TRAD_SYNOPSIS |
||
| 34 | #include |
||
| 35 | int remove(<[filename]>) |
||
| 36 | char *<[filename]>; |
||
| 37 | |||
| 38 | int _remove_r(<[reent]>, <[filename]>) |
||
| 39 | struct _reent *<[reent]>; |
||
| 40 | char *<[filename]>; |
||
| 41 | |||
| 42 | DESCRIPTION |
||
| 43 | Use < |
||
| 44 | filename (the string at <[filename]>) and the file it represents. |
||
| 45 | After calling < |
||
| 46 | longer be able to open the file by that name. |
||
| 47 | |||
| 48 | In this implementation, you may use < |
||
| 49 | error; existing file descriptors for the file will continue to access |
||
| 50 | the file's data until the program using them closes the file. |
||
| 51 | |||
| 52 | The alternate function <<_remove_r>> is a reentrant version. The |
||
| 53 | extra argument <[reent]> is a pointer to a reentrancy structure. |
||
| 54 | |||
| 55 | RETURNS |
||
| 56 | < |
||
| 57 | |||
| 58 | PORTABILITY |
||
| 59 | ANSI C requires < |
||
| 60 | failure be nonzero. The behavior of < |
||
| 61 | open file may vary among implementations. |
