eio_statvfs — Get file system statistics
说明
eio_statvfs() returns file system statistics information in
result argument of callback
参数
pathPathname of any file within the mounted file system
pri请求的优先级:
EIO_PRI_DEFAULT,EIO_PRI_MIN,EIO_PRI_MAX或null。如果是null,pri将设为EIO_PRI_DEFAULT。callbackcallback函数在请求完成时被调用。其应匹配一下原型:void callback(mixed $data, int $result[, resource $req]);data传递给请求的用户数据。
result针对请求的结果的值。通常是相应的系统调用返回的值。
req可选的请求资源,可被 eio_get_last_error() 之类的函数使用。
dataArbitrary variable passed to
callback.
返回值
eio_statvfs() returns request resource on success or
false on error. On success assigns result argument of
callback to an array.
范例
Example #1 eio_statvfs() example
<?php$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();?>
以上例程的输出类似于:
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)
