4272 the \textit{data} pointer is simply a pointer to another \textbf{ltc\_asn1\_list}.
4278 Decoding a SEQUENCE is similar to encoding. You set up an array of \textbf{ltc\_asn1\_list} where in this case the \textit{size} member is the maximum size
4332 and \textit{data} is \textbf{void} pointer. The list of items must be terminated with an item with the type \textbf{LTC\_ASN1\_EOL}.
4366 SETs use the same array structure of ltc\_asn1\_list that the SEQUENCE functions use. They are encoded with the following function:
