bool | opt_auto_adjust |
bool | opt_single_stream |

uint64_t | opt_block_size |
Compresses or uncompresses a file.
void coder_set_check | ( | lzma_check | check | ) |
Set the integrity check type used when compressing.
References check, and check_default.
void coder_set_preset | ( | uint32_t | new_preset | ) |
Set preset number.
References filters_count, lzma_filter::options, and preset_number.
void coder_set_extreme | ( | void | ) |
Enable extreme mode.
References preset_extreme.
void coder_add_filter | ( | lzma_vli | id, |
void * | options | ||
) |
Add a filter to the custom filter chain.
References filters_count, id, lzma_filter::id, LZMA_FILTERS_MAX, message_fatal(), and lzma_filter::options.
void coder_run | ( | const char * | filename | ) |
Compress or decompress the given file.
References lzma_stream::avail_in, coder_init(), coder_normal(), coder_passthru(), io_close(), io_open_dest(), io_open_src(), io_read(), message_filename(), message_progress_end(), message_progress_start(), lzma_stream::next_in, opt_mode, file_pair::src_st, and user_abort.
void coder_free | ( | void | ) |
Free the memory allocated for the coder and kill the worker threads.
References lzma_end().
enum operation_mode opt_mode |
Operation mode of the command line tool. This is set in args.c and read in several files.
Referenced by coder_init(), coder_normal(), coder_run(), message_filename(), message_mem_needed(), print_filename(), progress_pos(), and suffix_get_dest_name().
enum format_type opt_format |
File format to use when encoding or what format(s) to accept when decoding. This is a global because it's needed also in suffix.c. This is set in args.c.
Referenced by coder_init(), coder_normal(), compressed_name(), list_file(), and uncompressed_name().
bool opt_auto_adjust |
If true, the compression settings are automatically adjusted down if they exceed the memory usage limit.
bool opt_single_stream |
If true, stop after decoding the first stream.
Referenced by coder_init(), and coder_normal().
uint64_t opt_block_size |
If non-zero, start a new .xz Block after every opt_block_size bytes of input. This has an effect only when compressing to the .xz format.
