eio_statvfs — Get file system statistics
eio_statvfs() returns file system statistics information in
result argument of callback
pathPathname of any file within the mounted file system
pri請(qǐng)求的優(yōu)先級(jí):EIO_PRI_DEFAULT,EIO_PRI_MIN,EIO_PRI_MAX 或 null。如果是
null,pri 將設(shè)為
EIO_PRI_DEFAULT。
callback
callback
函數(shù)在請(qǐng)求完成時(shí)被調(diào)用。其應(yīng)匹配一下原型:
void callback(mixed $data, int $result[, resource $req]);
data傳遞給請(qǐng)求的用戶數(shù)據(jù)。
result針對(duì)請(qǐng)求的結(jié)果的值。通常是相應(yīng)的系統(tǒng)調(diào)用返回的值。
req可選的請(qǐng)求資源,可被 eio_get_last_error() 之類的函數(shù)使用。
data
Arbitrary variable passed to callback.
eio_statvfs() returns request resource on success, 或者在失敗時(shí)返回 false.
On success assigns result argument of
callback to an array.
示例 #1 eio_statvfs() example
<?php
$tmp_filename = '/tmp/eio-file.tmp';
touch($tmp_filename);
function my_statvfs_callback($data, $result) {
var_dump($data);
var_dump($result);
@unlink($data);
}
eio_statvfs($tmp_filename, EIO_PRI_DEFAULT, "my_statvfs_callback", $tmp_filename);
eio_event_loop();
?>
以上例程的輸出類似于:
string(17) "/tmp/eio-file.tmp"
array(11) {

int(4096)
["f_frsize"]=>
int(4096)

["f_bfree"]=>
int(262111)

["f_ffree"]=>
