eio_stat — Get file status
eio_stat() returns file status information in
result argument of callback
path
The file path
pri
请求的优先级: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or NULL.
如果是 NULL , pri 将设为
EIO_PRI_DEFAULT.
callback
callback 函数将在请求结束时被调用.
必须符合此原型:
void callback($data, $result);
$data 是传给该请求的特定数据.
$result 包含特定请求的结果值, 通常是相应的系统调用的返回值.
data
Arbitrary variable passed to callback.
eio_stat() returns request resource on success or
FALSE on error. On success assigns result argument of
callback to an array.
Example #1 eio_stat() example
<?php
$tmp_filename = "eio-file.tmp";
touch($tmp_filename);
function my_res_cb($data, $result) {
var_dump($data);
var_dump($result);
}
function my_open_cb($data, $result) {
eio_close($result);
eio_event_loop();
@unlink($data);
}
eio_stat($tmp_filename, EIO_PRI_DEFAULT, "my_res_cb", "eio_stat");
eio_open($tmp_filename, EIO_O_RDONLY, NULL,
EIO_PRI_DEFAULT, "my_open_cb", $tmp_filename);
eio_event_loop();
?>
以上例程的输出类似于：
string(8) "eio_stat"
array(12) {
