Function Documentation

dict_get()

static uint8_t dict_get ( const lzma_dict *const  dict, const uint32_t  distance  )

inlinestatic

Get a byte from the history buffer.

References lzma_dict::buf, lzma_dict::pos, and lzma_dict::size.

dict_is_empty()

static bool dict_is_empty ( const lzma_dict *const  dict )

inlinestatic

Test if dictionary is empty.

References lzma_dict::full.

dict_is_distance_valid()

static bool dict_is_distance_valid ( const lzma_dict *const  dict, const size_t  distance  )

inlinestatic

Validate the match distance.

References lzma_dict::full.

dict_repeat()

static bool dict_repeat ( lzma_dict *  dict, uint32_t  distance, uint32_t *  len  )

inlinestatic

Repeat *len bytes at distance.

dict_put()

static bool dict_put ( lzma_dict *  dict, uint8_t  byte  )

inlinestatic

Puts one byte into the dictionary. Returns true if the dictionary was already full and the byte couldn't be added.

dict_write()

static void dict_write ( lzma_dict *restrict  dict, const uint8_t *restrict  in, size_t *restrict  in_pos, size_t  in_size, size_t *restrict  left  )

inlinestatic

Copies arbitrary amount of data into the dictionary.
