+### Description
+
+The function `httplib_websocket_client_write()` sends data to a websocket server wrapped in a masked websocket frame. The function issues calls to [`httplib_lock_connection()`](httplib_lock_connection.md) and [`httplib_unlock_connection()`](httplib_unlock_connection.md) to ensure that the transmission is not interrupted. Interruption can happen the the application is proactively communicating and responding to a request simultaneously. This function is available only, if LibHTTP is compiled with the option `-DUSE_WEBSOCKET`.
+
+The return value is the number of bytes written on success, **0** when the connection has been closed and **-1** if an error occured.
