Passing data to and from liblzma.
The lzma_stream structure is used for
Typical usage:
Application may modify the values of total_in and total_out as it wants. They are updated by liblzma to match the amount of data read and written but aren't used for anything else except as a possible return values from lzma_get_progress().
const uint8_t* lzma_stream::next_in |
Pointer to the next input byte.
Referenced by lzma_code().
size_t lzma_stream::avail_in |
Number of available input bytes in next_in.
Referenced by coder_passthru(), and lzma_code().
uint64_t lzma_stream::total_in |
Total number of bytes read by liblzma.
Referenced by coder_passthru(), lzma_get_progress(), and progress_pos().
uint8_t* lzma_stream::next_out |
Pointer to the next output position.
Referenced by lzma_code().
size_t lzma_stream::avail_out |
Amount of free space in next_out.
Referenced by lzma_code().
uint64_t lzma_stream::total_out |
Total number of bytes written by liblzma.
Referenced by coder_passthru(), lzma_get_progress(), and progress_pos().
const lzma_allocator* lzma_stream::allocator |
Custom memory allocation functions.
In most cases this is NULL which makes liblzma use the standard malloc() and free().
Referenced by lzma_end(), and lzma_strm_init().
lzma_internal* lzma_stream::internal |
Internal state is not visible to applications.
Referenced by lzma_code(), lzma_end(), lzma_filters_update(), lzma_get_check(), lzma_get_progress(), lzma_memlimit_get(), lzma_memlimit_set(), lzma_memusage(), and lzma_strm_init().
uint64_t lzma_stream::seek_pos |
New seek input position for LZMA_SEEK_NEEDED.
When lzma_code() returns LZMA_SEEK_NEEDED, the new input position needed by liblzma will be available seek_pos. The value is guaranteed to not exceed the file size that was specified when this lzma_stream was initialized.
In all other situations the value of this variable is undefined.
