Returns: STATUS code of the execution. STATUS_SUCCESS on success

Here is the call graph for this function:

◆ signalingClientDeleteSync()

PUBLIC_API STATUS signalingClientDeleteSync ( SIGNALING_CLIENT_HANDLE signalingClientHandle )

Deletes the signaling channel referenced by SIGNALING_CLIENT_HANDLE.

NOTE: The function is intended to be used to clean up the backend resources and as such should be called at the end of the lifecycle of the signaling channel resource. Attempting to connect to the channel or send a message will result in an error or an unpredictable results after this call.

NOTE: The call transitions the signaling client state machine to a terminal state even if the call fails. The proper handling on success and on an error is to free the signaling client.

Parameters

[in] SIGNALING_CLIENT_HANDLE Signaling client handle

Returns: STATUS code of the execution. STATUS_SUCCESS on success

PUBLIC_API STATUS signalingClientGetIceConfigInfoCount	(	SIGNALING_CLIENT_HANDLE	signalingClientHandle,
		PUINT32	pIceConfigCount
	)

Gets the retrieved ICE configuration information object count.

NOTE: The call will fail if the client is not in the CONNECTED state.

Parameters

[in]	SIGNALING_CLIENT_HANDLE	Signaling client handle
[out]	PUINT32	The count of the ICE configuration information objects

Returns: STATUS code of the execution. STATUS_SUCCESS on success

◆ signalingClientGetStateString()

PUBLIC_API STATUS signalingClientGetStateString	(	SIGNALING_CLIENT_STATE	state,
		PCHAR *	ppStateStr
	)

Gets a literal string representing a Signaling client state.

Parameters

[in]	SIGNALING_CLIENT_HANDLE	Signaling client handle
[out]	PCHAR*	Read only string representing the state

Returns: STATUS code of the execution. STATUS_SUCCESS on success

◆ signalingClientSendMessageSync()

PUBLIC_API STATUS signalingClientSendMessageSync	(	SIGNALING_CLIENT_HANDLE	signalingClientHandle,
		PSignalingMessage	pSignalingMessage
	)

Send a message through a Signaling client.

NOTE: The call will fail if the client is not in the CONNECTED state. NOTE: This is a synchronous call. It will block and wait for sending the data and await for the ACK from the service.

Parameters

[in]	SIGNALING_CLIENT_HANDLE	Signaling client handle
[in]	PSignalingMessage	Message to send.

Returns: STATUS code of the execution. STATUS_SUCCESS on success
