$fd
,$mode
,$pri
= EIO_PRI_DEFAULT,$callback
= NULL,$data
= NULL
eio_fchmod() changes permissions for the file specified
by fd
file descriptor.
fd
Stream, Socket resource, or numeric file descriptor, e.g. returned by eio_open().
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_fchmod() returns request resource on success, or false
on failure.
