## ◆ reserved

uint8_t coap_dtls_spsk_t::reserved[7]

Set to COAP_DTLS_SPSK_SETUP_VERSION to support this version of the struct.

Reserved - must be set to 0 for future compatibility

Definition at line 470 of file coap_dtls.h.

## ◆ sni_call_back_arg

void* coap_dtls_spsk_t::sni_call_back_arg

Passed in to the SNI callback function.

Definition at line 493 of file coap_dtls.h.

## ◆ validate_id_call_back

coap_dtls_id_callback_t coap_dtls_spsk_t::validate_id_call_back

Identity check callback function.

If not `NULL`, is called when the Identity is provided by the client. The appropriate Pre-Shared Key to use can then be returned.

Definition at line 484 of file coap_dtls.h.

## ◆ validate_sni_call_back

coap_dtls_psk_sni_callback_t coap_dtls_spsk_t::validate_sni_call_back

SNI check callback function.

If not `NULL`, called if the SNI is not previously seen and prior to sending PSK information back to the client so that the appropriate PSK information can be used based on the requesting SNI.
