note 96534 added to function.dio-open

One of the prominent reasons to use direct IO, is for it's ability to do actual direct IO, bypassing the operating system cache and getting the data from the disk directly. The flag to do that (O_DIRECT) is missing from the documentation above. Maybe for good reasons, because this type of IO only works on blockdevices, not on files, and should only be used if you are **really** sure what you are doing. ---- Server IP: 69.147.83.197 Probable Submitter: 85.147.192.41 ---- Manual Page -- http://www.php.net/manual/en/function.dio-open.php Edit -- https://master.php.net/note/edit/96534 Del: integrated -- https://master.php.net/note/delete/96534/integrated Del: useless -- https://master.php.net/note/delete/96534/useless Del: bad code -- https://master.php.net/note/delete/96534/bad+code Del: spam -- https://master.php.net/note/delete/96534/spam Del: non-english -- https://master.php.net/note/delete/96534/non-english Del: in docs -- https://master.php.net/note/delete/96534/in+docs Del: other reasons-- https://master.php.net/note/delete/96534 Reject -- https://master.php.net/note/reject/96534 Search -- https://master.php.net/manage/user-notes.php
