-/**
- * \brief Calculates the alignment of the encoded output
- *
- * Knowing the alignment of the output data is useful e.g. in the Block
- * encoder which tries to align the Compressed Data field optimally.
- *
- * \param filters Pointer to lzma_filter array, whose last
- * member must have .id = LZMA_VLI_UNKNOWN.
- * \param guess The value to return if the alignment of the output
- * is the same as the alignment of the input data.
- * If you want to always detect this special case,
- * this guess to zero; this function never returns
- * zero unless guess is zero.
- *
- * \return In most cases, a small positive integer is returned;
- * for optimal use, the encoded output of this filter
- * chain should start at on offset that is a multiple of
- * the returned integer value.
- *
- * If the alignment of the output is the same as the input
- * data (which this function cannot know), \a guess is
- * returned.
- *
- * If an error occurs (that is, unknown Filter IDs or filter
- * options), UINT32_MAX is returned.
