Convert type struct klvanc_packet_eia_708b_s into a block of bytes which represents
an EIA-708 packet On success, caller MUST free the resulting *bytes array.
- Parameters
-
[in] | struct | klvanc_packet_eia_708b_s *pkt - A EIA-608 VANC entry, received from the EIA-708 parser |
[out] | uint8_t | **bytes - An array of bytes representing the serialized CDP packet |
[out] | uint16_t | *byteCount - Number of bytes in the array. |
- Returns
- 0 - Success

[in] | struct | klvanc_packet_eia_708bs *pkt - A EIA-708 VANC entry, received from the EIA-708 parser |
[out] | uint16_t | **words - An array of words representing a fully formed vanc line. |
[out] | uint16_t | *wordCount - Number of words in the array. |
