範例
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於:
string(17) "/tmp/eio-file.tmp" array(11) { ["f_bsize"]=> int(4096) ["f_frsize"]=> int(4096) ["f_blocks"]=> int(262144) ["f_bfree"]=> int(262111) ["f_bavail"]=> int(262111) ["f_files"]=> int(1540815) ["f_ffree"]=> int(1540743) ["f_favail"]=> int(1540743) ["f_fsid"]=> int(0) ["f_flag"]=> int(4102) ["f_namemax"]=> int(255) }
