Examples
Example #1 eio_lstat() example
<?php
$tmp_filename = dirname(__FILE__). "/eio-file.tmp";
touch($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($data);
}
eio_lstat($tmp_filename, EIO_PRI_DEFAULT, "my_res_cb", "eio_lstat");
eio_open($tmp_filename, EIO_O_RDONLY, NULL,
EIO_PRI_DEFAULT, "my_open_cb", $tmp_filename);
eio_event_loop();
?>
The above example will output something similar to:
string(9) "eio_lstat" array(12) { ["st_dev"]=> int(2050) ["st_ino"]=> int(2099197) ["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(1318235777) ["st_mtime"]=> int(1318235777) ["st_ctime"]=> int(1318235777) }
