Header for compress_lzma.c.

Definition in file compress_lzma.h.

Macro Definition Documentation

◆ tor_lzma_compress_free

#define tor_lzma_compress_free (   st)

Definition at line 35 of file compress_lzma.h.

Function Documentation

◆ tor_lzma_compress_free_()

void tor_lzma_compress_free_ ( tor_lzma_compress_state_t state)

Deallocate state.

Definition at line 328 of file compress_lzma.c.

◆ tor_lzma_compress_new()

tor_lzma_compress_state_t* tor_lzma_compress_new ( int  compress,
compress_method_t  method,
compression_level_t  level 

Construct and return a tor_lzma_compress_state_t object using method. If compress, it's for compression; otherwise it's for decompression.

Definition at line 174 of file compress_lzma.c.

◆ tor_lzma_compress_process()

tor_compress_output_t tor_lzma_compress_process ( tor_lzma_compress_state_t state,
char **  out,
size_t *  out_len,
const char **  in,
size_t *  in_len,
int  finish 

Compress/decompress some bytes using state. Read up to *in_len bytes from *in, and write up to *out_len bytes to *out, adjusting the values as we go. If finish is true, we've reached the end of the input.

Return TOR_COMPRESS_DONE if we've finished the entire compression/decompression. Return TOR_COMPRESS_OK if we're processed everything from the input. Return TOR_COMPRESS_BUFFER_FULL if we're out of space on out. Return TOR_COMPRESS_ERROR if the stream is corrupt.

Definition at line 245 of file compress_lzma.c.

◆ tor_lzma_compress_state_size()

size_t tor_lzma_compress_state_size ( const tor_lzma_compress_state_t state)

Return the approximate number of bytes allocated for state.

Definition at line 344 of file compress_lzma.c.

◆ tor_lzma_get_header_version_str()

const char* tor_lzma_get_header_version_str ( void  )

Return a string representation of the version of liblzma used at compilation time. Returns NULL if LZMA is unsupported.

Definition at line 108 of file compress_lzma.c.

◆ tor_lzma_get_total_allocation()

size_t tor_lzma_get_total_allocation ( void  )

Return the approximate number of bytes allocated for all LZMA states.

Definition at line 352 of file compress_lzma.c.

Referenced by tor_compress_get_total_allocation().

◆ tor_lzma_get_version_str()

const char* tor_lzma_get_version_str ( void  )

Return a string representation of the version of the currently running version of liblzma. Returns NULL if LZMA is unsupported.

Definition at line 96 of file compress_lzma.c.

◆ tor_lzma_init()

void tor_lzma_init ( void  )

Initialize the lzma module

Definition at line 359 of file compress_lzma.c.

Referenced by tor_compress_init().

◆ tor_lzma_method_supported()

int tor_lzma_method_supported ( void  )

Return 1 if LZMA compression is supported; otherwise 0.
