File SolidSyslogUdpPayload.h¶

FileList > Core > Interface > SolidSyslogUdpPayload.h

UDP payload sizing helpers: the usable payload for a given MTU and the UTF-8-safe trim used to fit a message into a datagram without splitting a codepoint.

#include <stdint.h>

Public Types Documentation¶

enum @5¶

Largest UDP payload guaranteed to fit an unfragmented IPv6 datagram: IPv6 minimum MTU 1280 - 40-byte IPv6 header - 8-byte UDP header (RFC 8200 §5).

enum @5 {
    SOLIDSYSLOG_UDP_IPV6_SAFE_PAYLOAD = 1232
};

Used as the last-resort MaxPayload when the OS cannot report a path MTU.

Public Functions Documentation¶

SolidSyslogUdpPayload_FromMtu¶

Usable UDP payload for an mtu , subtracting the IP header (40 for IPv6, 20 for IPv4) and the 8-byte UDP header.

size_t SolidSyslogUdpPayload_FromMtu (
    size_t mtu,
    bool isIpv6
)

SolidSyslogUdpPayload_TrimToCodepointBoundary¶

size_t SolidSyslogUdpPayload_TrimToCodepointBoundary (
    const uint8_t * buffer,
    size_t length
)
