+ * \brief Single-call .xz Stream decoder
+ *
+ * \param memlimit Pointer to how much memory the decoder is allowed
+ * to allocate. The value pointed by this pointer is
+ * modified if and only if LZMA_MEMLIMIT_ERROR is
+ * returned.
+ * \param flags Bitwise-or of zero or more of the decoder flags:
+ * LZMA_TELL_NO_CHECK, LZMA_TELL_UNSUPPORTED_CHECK,
+ * LZMA_CONCATENATED. Note that LZMA_TELL_ANY_CHECK
+ * is not allowed and will return LZMA_PROG_ERROR.
+ * \param allocator lzma_allocator for custom allocator functions.
+ * Set to NULL to use malloc() and free().
+ * \param in Beginning of the input buffer
+ * \param in_pos The next byte will be read from in[*in_pos].
+ * *in_pos is updated only if decoding succeeds.
+ * \param in_size Size of the input buffer; the first byte that
+ * won't be read is in[in_size].
+ * \param out Beginning of the output buffer
+ * \param out_pos The next byte will be written to out[*out_pos].
+ * *out_pos is updated only if encoding succeeds.
+ * \param out_size Size of the out buffer; the first byte into
+ * which no data is written to is out[out_size].
+ *
+ * \return - LZMA_OK: Decoding was successful.
+ * - LZMA_FORMAT_ERROR
+ * - LZMA_OPTIONS_ERROR
+ * - LZMA_DATA_ERROR
+ * - LZMA_NO_CHECK: This can be returned only if using
+ * the LZMA_TELL_NO_CHECK flag.
+ * - LZMA_UNSUPPORTED_CHECK: This can be returned only if using
+ * the LZMA_TELL_UNSUPPORTED_CHECK flag.
+ * - LZMA_MEM_ERROR
+ * - LZMA_MEMLIMIT_ERROR: Memory usage limit was reached.
+ * The minimum required memlimit value was stored to *memlimit.
