Field Documentation

◆ endpoint

unicoap_endpoint_t unicoap_memo_t::endpoint

The remote CoAP endpoint unicoap maintains an exchange with (client/server) or stores messaging state for.

Definition at line 234 of file state.h.

◆ [struct]

struct { ... } unicoap_memo_t::exchange

Exchange state.

State tracked by the request-response layer, i.e., client requests, block-wise transfers, and deferred responses.

◆ [union]

union { ... } unicoap_memo_t::messaging

Messaging state.

Note: There's no union for the underlying pointer type as drivers are allowed to keep their data structures private. This design avoids the need to expose every driver data structure.

◆ state

void* unicoap_memo_t::state

Messaging state.

Definition at line 226 of file state.h.

◆ timeout

unicoap_scheduled_event_t unicoap_memo_t::timeout

Timeout.
