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 LZMA_PRESET_LEVEL_MASK, and preset_number.
void coder_set_extreme | ( | void | ) |
Enable extreme mode.
References LZMA_PRESET_EXTREME, and preset_number.
void coder_add_filter | ( | lzma_vli | id, |
void * | options | ||
) |
Add a filter to the custom filter chain.
References filters_count, LZMA_FILTERS_MAX, and message_fatal().
void coder_run | ( | const char * | filename | ) |
Compress or decompress the given file.
References filename, io_open_src(), message_filename(), and opt_mode.
void coder_free | ( | void | ) |
Free the memory allocated for the coder and kill the worker threads.
References lzma_end(), and strm.
|
extern |
Operation mode of the command line tool. This is set in args.c and read in several files.
Referenced by coder_run(), message_filename(), message_mem_needed(), and mytime_get_flush_timeout().
|
extern |
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 list_file(), and uncompressed_name().
|
extern |
If true, the compression settings are automatically adjusted down if they exceed the memory usage limit.
|
extern |
If true, stop after decoding the first stream.
|
extern |
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.
|
extern |
This is non-NULL if –block-list was used. This contains the Block sizes as an array that is terminated with 0.
