Implementation of the networking functionality of the QUIC stack. This is where client and server instances are allocated and managed, taking care of actually sending data out, and to notify upper layers about new connections or data coming in. The networking stack relies on a separate event loop for polling the sockets.

Function Documentation

imquic_network_address_str()

char * imquic_network_address_str	(	imquic_network_address *	address,
		char *	output,
		size_t	outlen )

Helper to serialize a network address to a string.

Parameters

[in]	address	The imquic_network_address instance to serialize
[out]	output	The buffer to put the serialized string into
[in]	outlen	The size of the output buffer

Returns

A pointer to output, if successful, or NULL otherwise

imquic_network_endpoint_add_connection()

void imquic_network_endpoint_add_connection	(	imquic_network_endpoint *	ne,
		imquic_connection *	conn,
		gboolean	lock_mutex )

Helper to add a new connection to the list of connections originated by this endpoint.

Parameters

ne	The imquic_network_endpoint instance to add the connection to
conn	The imquic_connection instance to add to the endpoint
lock_mutex	Whether the endpoint mutex should be used to protect the action (to avoid double locks)

imquic_network_endpoint_create()

imquic_network_endpoint * imquic_network_endpoint_create

(

imquic_configuration *

config

)

Helper to create a new imquic_network_endpoint instance from a imquic_configuration object.

Parameters

config

The imquic_configuration object to use to configure and create the new endpoint

Returns

A pointer to a new imquic_network_endpoint instance, if successful, or NULL otherwise

imquic_network_endpoint_destroy()

void imquic_network_endpoint_destroy

(

imquic_network_endpoint *

ne

)

Helper to destroy an existing endpoint instance.

Parameters

ne	The imquic_network_endpoint instance to destroy

imquic_network_endpoint_remove_connection()

void imquic_network_endpoint_remove_connection	(	imquic_network_endpoint *	ne,
		imquic_connection *	conn,
		gboolean	lock_mutex )

Helper to remove an existing connection from the list of connections originated by this endpoint.

Parameters

ne	The imquic_network_endpoint instance to remove the connection from
conn	The imquic_connection instance to remove from the endpoint
lock_mutex	Whether the endpoint mutex should be used to protect the action (to avoid double locks)

imquic_network_endpoint_shutdown()

void imquic_network_endpoint_shutdown

(

imquic_network_endpoint *

ne

)

Helper to shutdown an existing endpoint.

Parameters

ne	The imquic_network_endpoint instance to shut down

imquic_network_send()

int imquic_network_send	(	imquic_connection *	conn,
		uint8_t *	bytes,
		size_t	blen )

Helper to send data on a connection.

Parameters

conn	The imquic_connection instance to send the data on
bytes	The data to send
blen	the size of the data to send

Returns

0 in case of success, a negative integer otherwise
