Field Documentation

block_size

size_t block_size

Start a new Block every block_size bytes of input unless LZMA_FULL_FLUSH or LZMA_FULL_BARRIER is used earlier.

cond

mythread_cond cond

filters

lzma_filter filters

The filter chain to use for the next Block. This can be updated using lzma_filters_update() after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH.

filters_cache

lzma_filter filters_cache

A copy of filters[] will be put here when attempting to get a new worker thread. This will be copied to a worker thread when a thread becomes free and then this cache is marked as empty by setting [0].id = LZMA_VLI_UNKNOWN. Without this cache the filter options from filters[] would get uselessly copied multiple times (allocated and freed) when waiting for a new free worker thread.

This is freed if filters[] is updated via lzma_filters_update().

header

uint8_t header

Buffer to hold Stream Header and Stream Footer.

header_pos

size_t header_pos

Read position in header[].

index

lzma_index * index

Index to hold sizes of the Blocks.

index_encoder

lzma_next_coder index_encoder

Index encoder.

mutex

mythread_mutex mutex

outbuf_alloc_size

size_t outbuf_alloc_size

How much memory to allocate for each lzma_outbuf.buf.

outq

lzma_outq outq

Output buffer queue for compressed data.

progress_in

uint64_t progress_in

Amount of uncompressed data in Blocks that have already been finished.

progress_out

uint64_t progress_out

Amount of compressed data in Stream Header + Blocks that have already been finished.

[] [1/3]

enum { ... } sequence

[] [2/3]

enum { ... } sequence

[] [3/3]

enum { ... } sequence

stream_flags

lzma_stream_flags stream_flags

Stream Flags for encoding the Stream Header and Stream Footer.

thr

worker_thread * thr

The most recent worker thread to which the main thread writes the new input from the application.

thread_error

lzma_ret thread_error

Error code from a worker thread.

threads

worker_thread * threads

Array of allocated thread-specific structures.

threads_free

worker_thread * threads_free

Stack of free threads. When a thread finishes, it puts itself back into this stack. This starts as empty because threads are created only when actually needed.

threads_initialized

uint32_t threads_initialized

Number of thread structures that have been initialized, and thus the number of worker threads actually created so far.

threads_max

uint32_t threads_max

Number of structures in "threads" above. This is also the number of threads that will be created at maximum.

timeout

uint32_t timeout

Maximum wait time if cannot use all the input and cannot fill the output buffer. This is in milliseconds.
