+|**`conn`**|`struct httplib_connection *`|Connection on which the data must be written|
+|**`opcode`**|`int`|Opcode|

+|**`data_len`**|`size_t`|Length of the data|
+
+### Return Value

+| :--- | :--- |
+|`int`|Number of bytes written or an error code|
+
+### Description
+
+The function `httplib_websocket_write()` sends data to a websocket client wrapped in a websocket frame. The function issues calls to [`httplib_lock_connection()`](httplib_lock_connection.md) and [`httplib_unlock_connaction()`](httplib_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.
+
+The function is available only when LibHTTP is compiled with the `-DUSE_WEBSOCKET` option.
+
+The function returns the number of bytes written, **0** when the connection has been closed and **-1** if an error occured.
