eio_chown — Change file/directory ownership

Description

function eio_chown(
    string $path,
    int $uid,
    int $gid = -1,
    int $pri = EIO_PRI_DEFAULT,
    callable $callback = NULL,
    mixed $data = NULL
): resource

eio_chown() changes ownership of a file, or directory. The new owner is specified by uid, and the group by gid.

Parameters

path

Path to file or directory.

Warning

Avoid relative paths

uid

User ID. Is ignored when equal to -1.

gid

Group ID. Is ignored when equal to -1.

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.

Return Values

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