Functions

imquic_serverimquic_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_clientimquic_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 MoQ 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 this is where you need to configure the MoQ role via imquic_moq_set_role. 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.
 
void imquic_set_moq_ready_cb (imquic_endpoint *endpoint, void(*moq_ready)(imquic_connection *conn))
 Configure the callback function to be notified when a MoQ connection has been successfully established. After this, the MoQ APIs can be used to start exchanging MoQ messages.

Detailed Description

imquic MoQ public interface

Author
Lorenzo Miniero loren.nosp@m.zo@m.nosp@m.eetec.nosp@m.ho.c.nosp@m.om

Public interface to the Media Over QUIC (MoQ) native support in the imquic library. This is where public functions are callbacks to interact with the MoQ features of the library are defined.

◆ 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_HTTP3_PATH, "/moq",
        IMQUIC_CONFIG_DONE, NULL);

to create a QUIC client that will automatically negotiate MoQ over WebTransport. Notice that the MoQ role (publisher, subscriber or relay) is not set here: this is only specifying the QUIC role (client). For the MoQ role, see the imquic_set_new_moq_connection_cb callback and imquic_moq_set_role. Again, 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]nameThe 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_DONE, NULL);

to create a QUIC server that will automatically negotiate MoQ over WebTransport. Notice that the MoQ role (publisher, subscriber or relay) is not set here: this is only specifying the QUIC role (server). For the MoQ role, see the imquic_set_new_moq_connection_cb callback and imquic_moq_set_role.
