| * \brief Initializes raw encoder |

| * This function may be useful when implementing custom file formats. |

| * \param strm Pointer to properly prepared lzma_stream |
| * \param options Array of lzma_options_filter structures. |
| * The end of the array must be marked with |
| * .id = LZMA_VLI_VALUE_UNKNOWN. The minimum |
| * number of filters is zero; the maximum is |
| * determined by available memory. |
| * \param uncompressed_size |
| * Size of the uncompressed data. If it is unknown, |
| * use LZMA_VLI_VALUE_UNKNOWN. You need to give the |
| * same value to the raw decoder to decode the data. |
| * \param allow_implicit |
| * If true, an implicit Copy or Subblock filter should be |
| * automatically added when needed. If this is false and |
| * an implicit filter would be needed, LZMA_PROG_ERROR is |
| * returned. |
| * |
| * The `action' with lzma_code() can be LZMA_RUN, LZMA_SYNC_FLUSH (if the |
| * filter chain support it), or LZMA_FINISH. |
| * |
| * \return - LZMA_OK |
| * - LZMA_MEM_ERROR |
| * - LZMA_HEADER_ERROR |
| * - LZMA_PROG_ERROR |
