F`int woz_aliro_tlv_next(const uint8_t data, size_t data_length, size_t offset, struct woz_aliro_tlv *out)`

modules/woz_aliro_stack/src/protocol/tlv.c:7

Parse one TLV at *offset and advance the offset past it. Indefinite and non-minimal DER lengths are rejected.

F`size_t woz_aliro_tlv_encoded_size(uint32_t tag, size_t value_length)`

modules/woz_aliro_stack/src/protocol/tlv.c:101

Return the encoded size of a definite-length TLV, or zero when the tag or length cannot be represented by this codec. Tags are supplied in their normal big-endian encoded form (for example 0x7f66).
