🎀 SYNOPSIS 🎀

int parse_OID (const void *data , size_t datasize , enum OID *oid );

---

🌸 ARGUMENTS 🌸

• data — the binary representation of the header + OID, iconic input vibes 💅
• datasize — the size of that binary representation, gotta know the size bestie
• oid — pointer to oid where the result gets returned 🫶

---

✨ DESCRIPTION ✨

So parse_OID parses an OID from a bytestream that holds the OID in the format ASN1_OID | length | oid. no cap.

The length indicator must equal to datasize - 2. like, that's the rule.

If the bytestream is too short, -EBADMSG is returned. 😭 that's the whole warning, bestie.

ngl, short bytestream = -EBADMSG return. periodt.
