eio_chmod — Change file/direcrory permissions

说明

eio_chmod ( string $path , int $mode [, int $pri = EIO_PRI_DEFAULT [, callable $callback = NULL [, mixed $data = NULL ]]] ) : resource

eio_chmod() changes file, or direcrory permissions. The new permissions are specified by mode.

参数

path

Path to the target file or directory

Warning

避免相对路径。

mode

The new permissions. E.g. 0644.

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。

callback

callback 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。

data

Arbitrary variable passed to callback.

返回值

eio_chmod() returns request resource on success or FALSE on error.
