| Name | Description |
|---|---|
| timeout [in] | Wait this much for at least one of the requested events to occur. |
| requested [in] | Wait for those events, bitwise-or of RecvEvent and SendEvent. |
| occurred [out] | If not nullptr and the function returns true, then this indicates which of the requested events occurred (ErrorEvent will be added, even if not requested, if an exceptional event occurs on the socket). A timeout is indicated by return value of true and occurred being set to 0. |
