| #define PACKED_INDEX_LIST_SIZE | ( | INDEX_COUNT | ) | (((INDEX_COUNT) / 2) * 3 + ((INDEX_COUNT) & 1) * 2) |
Calculates the size of a packed index list.
Every pair of indexes needs 3 octets. If the number of octets is odd, the last octet needs 2 octets by itself.
| [in] | INDEX_COUNT | Number of indexes that the list will contain. |

Creates a packed index list.
| [in] | p_index_list | List of indexes to pack into the output list. |
| [out] | p_packed_list | Pointer to the start of a buffer where the packed index list is written. The size that this buffer must have can be obtained by using PACKED_INDEX_LIST_SIZE. |
| [in] | index_count | Number of indexes to store in the packed index list. |
