Function Documentation

concat_and_insert()

std::vector< uint8_t > stream::concat_and_insert	(	uint64_t	insert_size,
		uint64_t	slice_size,
		const std::string_view &	data1,
		const std::string_view &	data2 )

Combines two buffers and inserts new buffers at each slice boundary of the result.

Parameters

insert_size	The number of bytes to insert.
slice_size	The number of bytes between insertions.
data1	The first data buffer.
data2	The second data buffer.

send_feedback_msg()

int stream::send_feedback_msg	(	session_t *	session,
		platf::gamepad_feedback_msg_t &	msg )

Pass gamepad feedback data back to the client.

Parameters

session	The session object.
msg	The message to pass.

Returns

0 on success.
