eio_chmod — Change file/directory permissions

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

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

path

Path to the target file or directory

Warning

Avoid relative paths

mode

The new permissions. E.g. 0644.

pri

The request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or null. If null passed, pri internally is set to EIO_PRI_DEFAULT.

callback

callback function is called when the request is done. It should match the following prototype:

void callback(mixed $data, int $result[, resource $req]);

data: is custom data passed to the request.
result: request-specific result value; basically, the value returned by corresponding system call.
req: is optional request resource which can be used with functions like eio_get_last_error().

data

Arbitrary variable passed to callback.

eio_chmod() returns request resource on success, or false on failure.
