• indices: The index range of each feature is [0, ntotal). ntotal can be obtained through the GetNTotal API.
• n: The value range is [0, capacity].
• indices must be a non-null pointer and its length must meet the requirements. Otherwise, an out-of-bounds read/write error may occur, causing program breakdown.
