libnvmf_tid_get_canonical(9)

💖 NAME 💖

okay so this is the libnvmf_tid_get_canonical(9) page from the libnvme API manual ✨ buckle up bestie, it’s actually super straightforward 🫶

libnvmf_tid_get_canonical — return the canonical string form of a TID. periodt 💅

🌸 SYNOPSIS 🌸

const char * libnvmf_tid_get_canonical (const struct libnvmf_tid *tid );

🎀 ARGUMENTS 🎀

• tid — the transport ID. that’s the whole assignment, no cap 🦋

✨ DESCRIPTION ✨

bestie, this function hands you back a deterministic, fixed-field-order, semicolon-separated key=value string — like "transport=tcp;traddr=1.2.3.4;trsvcid=8009" 🌸 only non-NULL fields make it in. the string is lazily computed and cached; any identity change invalidates it. it’s giving “efficient and correct” 💅

the way the field order is fixed means the output doesn’t care what order the fields were set in — same logical TID, same canonical string, every time 💖 this is the stable primitive libnvme gives you for naming a connection; if a caller wants a compact hash (e.g. for a systemd unit name), it derives that from this string itself — libnvme does not hash it. iykyk 😌

also, the constructors store numeric addresses in one form: IPv6 is compressed, and an IPv4-mapped IPv6 address ("::ffff:1.2.3.4") becomes the IPv4 address ("1.2.3.4") 🦋 so two spellings of one numeric address yield the same canonical string. iconic behavior, honestly 👑

🔥 RETURN 🔥

the cached canonical string, or NULL on allocation failure 😭
