Single-call .xz Index decoder. |
Decodes the Index field.
lzma_ret lzma_index_decoder | ( | lzma_stream * | strm, | |
lzma_index ** | i, | |||
uint64_t | memlimit | |||
) |
Initialize .xz Index decoder.
strm | Pointer to properly prepared lzma_stream | |
i | Pointer to a pointer that will be made to point to the final decoded Index once lzma_code() has returned LZMA_STREAM_END. That is, lzma_index_decoder() always takes care of allocating a new lzma_index structure, and *i doesn't need to be initialized by the caller. | |
memlimit | How much memory the resulting Index is allowed to require. |
The only valid action value for lzma_code() is LZMA_RUN.

) |
Single-call .xz Index decoder.
i | Pointer to a pointer that will be made to point to the final decoded Index if decoding is successful. That is, lzma_index_buffer_decode() always takes care of allocating a new lzma_index structure, and *i doesn't need to be initialized by the caller. | |
memlimit | Pointer to how much memory the resulting Index is allowed to require. The value pointed by this pointer is modified if and only if LZMA_MEMLIMIT_ERROR is returned. | |
allocator | Pointer to lzma_allocator, or NULL to use malloc() | |
in | Beginning of the input buffer | |
in_pos | The next byte will be read from in[*in_pos]. *in_pos is updated only if decoding succeeds. | |
in_size | Size of the input buffer; the first byte that won't be read is in[in_size]. |
