note 129891 added to ref.shmop

Despite the fact that reads from and writes to the shared memory are not atomic, reading and writing just ONE byte is always atomic. This can be very useful if your application frequently reads and rarely writes "small" chunks of data (~10-15 bytes). You can avoid using any kind of locks by signing your data by 8-bit checksum (like CRC-8). This is an effective and reliable way to ensure that your data is not corrupted. The redundancy is naturally 8 bits. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 46.39.51.215) ---- Manual Page -- https://php.net/manual/en/ref.shmop.php Edit -- https://main.php.net/note/edit/129891 Del: integrated -- https://main.php.net/note/delete/129891/integrated Del: useless -- https://main.php.net/note/delete/129891/useless Del: bad code -- https://main.php.net/note/delete/129891/bad+code Del: spam -- https://main.php.net/note/delete/129891/spam Del: non-english -- https://main.php.net/note/delete/129891/non-english Del: in docs -- https://main.php.net/note/delete/129891/in+docs Del: other reasons-- https://main.php.net/note/delete/129891 Reject -- https://main.php.net/note/reject/129891 Search -- https://main.php.net/manage/user-notes.php
