UDP transport over a FreeRTOS-Plus-TCP socket, for a UdpSender. More...

#include "ExternC.h"

Public Functions¶

Type	Name
struct SolidSyslogDatagram *	SolidSyslogPlusTcpDatagram_Create (void) Create takes no config; an exhausted pool falls back to the shared NullDatagram, whose SendTo reports SENT so undeliverables are dropped rather than backing up the Store.
void	SolidSyslogPlusTcpDatagram_Destroy (struct SolidSyslogDatagram * base) Release the pool slot and close the socket.

Detailed Description¶

SendTo wraps FreeRTOS_sendto (unconnected, destination per call) and reports SENT when the stack accepts the whole datagram, else FAILED. On an ARP-cache miss it first issues an ARP probe and yields once (~50 ms) for the reply, because FreeRTOS-Plus-TCP does not queue datagrams while ARP resolves — the cold-start packet would otherwise be dropped at the IP layer; if the reply is late the send is left to fail, since UDP is best-effort and retry belongs in the store-and-forward layer above. MaxPayload is the fixed IPv6-safe default.
