37 /* DESCRIPTION */
38 /* */
39 /* This function starts a DTLS session for a DTLS server. It is */
40 /* intended for use with the DTLS Server API - when a DTLS server */
41 /* instance invokes the DTLS connection callback, this function is */
42 /* used by the application to kick off the DTLS handshake. It may also */
43 /* be used for single DTLS sessions but note that the UDP socket must */
44 /* be initialized and ready for send/receive operations prior to */
45 /* calling this service. */
