eio_statGet file status

Description

resource eio_stat ( string $path , int $pri , callable $callback [, mixed $data = NULL ] )

eio_stat() returns file status information in result argument of callback

Parameters

path

The file path

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_stat() returns request resource on success or FALSE on error. On success assigns result argument of callback to an array.

Examples

Example #1 eio_stat() example

<?php
$tmp_filename 
"eio-file.tmp";
touch($tmp_filename);

function 
my_res_cb($data$result) {
    
var_dump($data);
    
var_dump($result);
}

function 
my_open_cb($data$result) {
    
eio_close($result);
    
eio_event_loop();

    @
unlink($data);
}

eio_stat($tmp_filenameEIO_PRI_DEFAULT"my_res_cb""eio_stat");
eio_open($tmp_filenameEIO_O_RDONLYNULL,
 
EIO_PRI_DEFAULT"my_open_cb"$tmp_filename);
eio_event_loop();
?>

The above example will output something similar to:

 string(8) "eio_stat" array(12) { ["st_dev"]=> int(2050) ["st_ino"]=> int(2489173) ["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(1318250380) ["st_mtime"]=> int(1318250380) ["st_ctime"]=> int(1318250380) }
