ngtcp2_conn_get_active_dcid2

Synopsis

#include <ngtcp2/ngtcp2.h>

size_t ngtcp2_conn_get_active_dcid2(ngtcp2_conn *conn, ngtcp2_cid_token2 *dest)

ngtcp2_conn_get_active_dcid2() writes the all active Destination Connection IDs and their tokens to dest. Before handshake completes, this function returns 0. If dest is NULL, this function does not write anything, and returns the number of Destination Connection IDs that would otherwise be written to the provided buffer. The buffer pointed by dest must have sizeof(ngtcp2_cid_token2) * n bytes available, where n is the return value of ngtcp2_conn_get_active_dcid2() with dest == NULL.

This function has been available since v1.22.0.
