eio_fstat — Get file status
eio_fstat() returns file status information in
result
argument of callback
fd
Stream, Socket resource, or numeric file descriptor.
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_busy() returns request resource on success, o false
in caso di fallimento.
Example #1 eio_lstat() example
<?php
// Create temporary file
$tmp_filename = dirname(__FILE__) ."/eio-file.tmp";
touch($tmp_filename);
/* Is called when eio_fstat() done */
function my_res_cb($data, $result) {
// Should output array with stat info
var_dump($result);
if ($data['fd']) {
// Close temporary file
eio_close($data['fd']);
eio_event_loop();
}
// Remove temporary file
@unlink($data['file']);
}
/* Is called when eio_open() done */
function my_open_cb($data, $result) {
// Prepare data for callback
$d = array(
'fd' => $result,
'file'=> $data
);
// Request stat info
eio_fstat($result, EIO_PRI_DEFAULT, "my_res_cb", $d);
// Process request(s)
eio_event_loop();
}
// Open temporary file
eio_open($tmp_filename, EIO_O_RDONLY, NULL, EIO_PRI_DEFAULT,
"my_open_cb", $tmp_filename);
eio_event_loop();
?>
Il precedente esempio visualizzerà qualcosa simile a:
array(12) { ["st_dev"]=> int(2050) ["st_ino"]=> int(2489159) ["st_mode"]=> int(33188) ["st_nlink"]=> int(1) ["st_uid"]=> int(1000) ["st_gid"]=> int(100) ["st_rdev"]=> int(0) ["st_blksize"]=> int(4096) ["st_blocks"]=> int(0) ["st_atime"]=> int(1318239506) ["st_mtime"]=> int(1318239506) ["st_ctime"]=> int(1318239506) }
