范例
Example #1 eio_statvfs() example
<?php$tmp_filename = '/tmp/eio-file.tmp';touch($tmp_filename);function my_statvfs_callback($data, $result) { var_dump($data); var_dump($result); @unlink($data);}eio_statvfs($tmp_filename, EIO_PRI_DEFAULT, "my_statvfs_callback", $tmp_filename);eio_event_loop();?>
以上例程的输出类似于:
string(17) "/tmp/eio-file.tmp" array(11) { ["f_bsize"]=> int(4096) ["f_frsize"]=> int(4096) ["f_blocks"]=> int(262144) ["f_bfree"]=> int(262111) ["f_bavail"]=> int(262111) ["f_files"]=> int(1540815) ["f_ffree"]=> int(1540743) ["f_favail"]=> int(1540743) ["f_fsid"]=> int(0) ["f_flag"]=> int(4102) ["f_namemax"]=> int(255) }
