函数名称：Decode the Number of Records, Unpadded Size, and Uncompressed Size* fields from the Index field. That is, Index Padding and CRC32 are not* decoded by this function.* This can return XZ_OK (more input needed), XZ_STREAM_END (everything

函数原型：static enum xz_ret dec_index(struct xz_dec *s, struct xz_buf *b)

返回类型：enum xz_ret

参数：

类型参数名称
struct xz_dec *s
struct xz_buf *b
300  循环
301  ret等于Decode a variable-length integer (little-endian base-128 encoding)
302  如果ret不等于XZ_STREAM_END则
303  Update the Index size and the CRC32 value.
304  返回:ret
308  当:Position in dec_index() 恒等于SEQ_INDEX_COUNT
322  当:Position in dec_index() 恒等于SEQ_INDEX_UNPADDED
327  当:Position in dec_index() 恒等于SEQ_INDEX_UNCOMPRESSED
337  当Number of Records (matches block.count in valid files) 大于0循环
339  返回:XZ_STREAM_END
