 ### Description
 
-The function `mg_websocket_write()` sends data to a websocket client wrapped in a websocket frame. The function issues calls to [`mg_lock_connection()`](mg_lock_connection.md) and [`mg_unlock_connaction()`](mg_unlock_connection.md) to ensure that the transmission is not interrupted. Data corruption can otherwise happn if the application is proactively communicating and responding to a request simultaneously.
