Functions
const char *	imquic_moq_auth_token_alias_type_str (imquic_moq_auth_token_alias_type type)
	Helper function to serialize to string the name of a imquic_moq_auth_token_alias_type property.
int	imquic_moq_parse_auth_token (uint8_t *bytes, size_t blen, imquic_moq_auth_token *token)
	Helper mode to parse an auth token buffer to a imquic_moq_auth_token instance.

	Helper mode to craft an auth token buffer out of a imquic_moq_auth_token instance.
const char *	imquic_moq_version_str (imquic_moq_version version)
	Helper function to serialize to string the name of a imquic_moq_version property.
imquic_moq_version	imquic_moq_get_version (imquic_connection *conn)
	Helper function to get the MoQ version associated with a connection.
int	imquic_moq_set_connection_auth (imquic_connection *conn, uint8_t *auth, size_t authlen)
	Method to provide credentials, as a client, on a new connection. If credentials need to provided, this must be done as soon as the connection is established, and before sending any MoQ message. A good place to do that is the callback fired when a new connection is available.
int	imquic_moq_set_max_request_id (imquic_connection *conn, uint64_t max_request_id)
	Helper function to set the Maximum Request ID a subscriber can send.
uint64_t	imquic_moq_get_next_request_id (imquic_connection *conn)

const char *	imquic_moq_get_remote_implementation (imquic_connection *conn)
	Helper function to return the MoQ implementation name as a string, if provided by the peer of this connection.
MoQ endpoints management
imquic_server *	imquic_create_moq_server (const char *name,...)
	Method to create a new MoQ server, using variable arguments to dictate what the server should do (e.g., port to bind to, ALPN, etc.). Variable arguments are in the form of a sequence of name-value started with a IMQUIC_CONFIG_INIT and ended by a IMQUIC_CONFIG_DONE , e.g.:
imquic_client *	imquic_create_moq_client (const char *name,...)
	Method to create a new MoQ client, using variable arguments to dictate what the client should do (e.g., address to connect to, ALPN, etc.). Variable arguments are in the form of a sequence of name-value started with a IMQUIC_CONFIG_INIT and ended by a IMQUIC_CONFIG_DONE , e.g.:
void	imquic_set_new_moq_connection_cb (imquic_endpoint *endpoint, void(*new_moq_connection)(imquic_connection *conn, void *user_data))
	Configure the callback function to be notified about new QUIC connections on the configured endpoint. For a server, it will be triggered any time a client successfully connects to the server; for a client, it will be triggered when the client successfully connects to the server. Notice that this precedes the MoQ setup/handshakes, which means you'll need to wait until the callback set in imquic_set_moq_ready_cb is fired, before being able to use the MoQ API for publishing/subscribing.

	Configure the callback function to be notified, as a server, when a CLIENT_SETUP is received. This is a chance, for instance, to evaluate the credentials that were provided. It's the application responsibility to accept or reject the connection at this point: returning 0 will accept the connection, while returning an error code will reject and close it. Connections are automatically accepted if this callback is not configured.
void	imquic_set_moq_ready_cb (imquic_endpoint *endpoint, void(*moq_ready)(imquic_connection *conn))

Generic error codes.

imquic_moq_extension_type

typedef enum imquic_moq_extension_type imquic_moq_extension_type

Known MoQ Object Extension header types.

Note

The library will not try to interpret extensions and their payload: this is always left up to applications

imquic_moq_filter_type

typedef enum imquic_moq_filter_type imquic_moq_filter_type

MoQ filter type, for subscriptions.

imquic_moq_group_order

typedef enum imquic_moq_group_order imquic_moq_group_order

Group ordering for tracks.

MoQ Track Name.

imquic_moq_namespace

typedef struct imquic_moq_namespace imquic_moq_namespace

MoQ Track Namespace.

imquic_moq_object

typedef struct imquic_moq_object imquic_moq_object

MoQ Object.

Note

This may contain info related to different MoQ versions, and so should be considered a higher level abstraction that the internal MoQ stack may (and often will) use and notify differently

imquic_moq_object_extension

typedef struct imquic_moq_object_extension imquic_moq_object_extension

MoQ Object Extension.

Note

This may contain info related to different MoQ versions, and so should be considered a higher level abstraction that the internal MoQ stack may (and often will) use and notify differently

imquic_moq_object_status

typedef enum imquic_moq_object_status imquic_moq_object_status

imquic_moq_request_parameters

typedef struct imquic_moq_request_parameters imquic_moq_request_parameters

MoQ request parameters.

Note

This struct is used in the MoQ API signatures even when the negotiated version of MoQ is lower than v15, that is when most of the properties below were fields in the messages themselves, rather than parameters as they are now. The library takes care of the serialization/deserialization process automatically, so you can refer to this struct from an application perspective, and the library will take care of the rest. Notice that not all of these parameters are supported in all MoQ requests and responses, which means that the library will silently ignore parameters that are not supposed to be there in case.

typedef enum imquic_moq_reset_stream_code imquic_moq_reset_stream_code

RESET_STREAM error codes.

imquic_moq_subscribe_namespace_options

Function Documentation

imquic_create_moq_client()

imquic_client * imquic_create_moq_client	(	const char *	name,
			... )

Method to create a new MoQ client, using variable arguments to dictate what the client should do (e.g., address to connect to, ALPN, etc.). Variable arguments are in the form of a sequence of name-value started with a IMQUIC_CONFIG_INIT and ended by a IMQUIC_CONFIG_DONE , e.g.:

       imquic_server *client = imquic_create_moq_client("moq-sub",
        IMQUIC_CONFIG_INIT,
        IMQUIC_CONFIG_TLS_CERT, cert_pem,
        IMQUIC_CONFIG_TLS_KEY, cert_key,
        IMQUIC_CONFIG_TLS_PASSWORD, cert_pwd,
        IMQUIC_CONFIG_REMOTE_HOST, "127.0.0.1",
        IMQUIC_CONFIG_REMOTE_PORT, 9000,
        IMQUIC_CONFIG_WEBTRANSPORT, TRUE,
        IMQUIC_CONFIG_MOQ_VERSION, IMQUIC_MOQ_VERSION_16,
        IMQUIC_CONFIG_HTTP3_PATH, "/moq",
        IMQUIC_CONFIG_DONE, NULL);

to create a QUIC client that will automatically negotiate MoQ over WebTransport. Notice that this only specifies the QUIC role (client), not what role the application will have with respect to MoQ. Again, notice that, axacrlt as with imquic_create_client, this will only create the resource, but not actually start the connection: before doing that, you'll need to configure the callbacks for the events you're interested in (in this case, MoQ specific), and then use imquic_start_endpoint to start the QUIC client (which will attempt a connection).

Note

This will create a full, internal, MoQ stack on top of imquic, meaning that the MoQ Transport protocol will be handled natively by imquic for you, providing a high level interface to the features of the protocol itself. If you want to only use imquic as a QUIC/WebTrasport protocol, and implement MoQ yourself, then you'll need to use imquic_create_server or imquic_create_client instead.

Parameters

[in]

name

The endpoint name (if NULL, a default value will be set)

Returns

A pointer to a imquic_client object, if successful, NULL otherwise

imquic_create_moq_server()

imquic_server * imquic_create_moq_server	(	const char *	name,
			... )

Method to create a new MoQ server, using variable arguments to dictate what the server should do (e.g., port to bind to, ALPN, etc.). Variable arguments are in the form of a sequence of name-value started with a IMQUIC_CONFIG_INIT and ended by a IMQUIC_CONFIG_DONE , e.g.:

       imquic_server *server = imquic_create_moq_server("moq-relay",
        IMQUIC_CONFIG_INIT,
        IMQUIC_CONFIG_TLS_CERT, cert_pem,
        IMQUIC_CONFIG_TLS_KEY, cert_key,
        IMQUIC_CONFIG_TLS_PASSWORD, cert_pwd,
        IMQUIC_CONFIG_LOCAL_PORT, 9000,
        IMQUIC_CONFIG_WEBTRANSPORT, TRUE,
        IMQUIC_CONFIG_MOQ_VERSION, IMQUIC_MOQ_VERSION_16,
        IMQUIC_CONFIG_DONE, NULL);

to create a QUIC server that will automatically negotiate MoQ over WebTransport. Notice that this only specifies the QUIC role (server), not what role the application will have with respect to MoQ. Againn notice that, exactly as with imquic_create_server, this will only create the resource, but not actually start the server: before doing that, you'll need to configure the callbacks for the events you're interested in (in this case, MoQ specific), and then use imquic_start_endpoint to start the QUIC server (which will wait for incoming connections).

Note

This will create a full, internal, MoQ stack on top of imquic, meaning that the MoQ Transport protocol will be handled natively by imquic for you, providing a high level interface to the features of the protocol itself. If you want to only use imquic as a QUIC/WebTrasport protocol, and implement MoQ yourself, then you'll need to use imquic_create_server or imquic_create_client instead.
