| [section:SettableSocketOption Settable socket option requirements] |
| |
| A type `X` meets the `SettableSocketOption` requirements if it satisfies the |
| requirements listed below. |
| |
| In the table below, `a` denotes a (possibly const) value of type `X`, `p` |
| denotes a (possibly const) value that meets the [link asio.reference.Protocol |
| `Protocol`] requirements, and `u` denotes an identifier. |
