24 * A QUIC Port (QUIC_PORT) represents a single UDP network socket and contains
25 * zero or more subsidiary QUIC_CHANNEL instances, each of which represents a
26 * single QUIC connection. All QUIC_CHANNEL instances must belong to a
29 typedef struct quic_port_args_st {
30 /* All channels in a QUIC event domain share the same (libctx, propq). */
35 * This must be a mutex the lifetime of which will exceed that of the port
36 * and all channels. The instantiator of the port is responsible for
37 * providing a mutex as this makes it easier to handle instantiation and
38 * teardown of channels in situations potentially requiring locking.
40 * Note that this is a MUTEX not a RWLOCK as it needs to be an OS mutex for
41 * compatibility with an OS's condition variable wait API, whereas RWLOCK
42 * may, depending on the build configuration, be implemented using an OS's
43 * mutex primitive or using its RW mutex primitive.
48 * Optional function pointer to use to retrieve the current time. If NULL,
49 * ossl_time_now() is used.
