.xz Stream Header and Stream Footer encoder and decoder
| #define LZMA_STREAM_HEADER_SIZE 12 |
Size of Stream Header and Stream Footer.
Stream Header and Stream Footer have the same size and they are not going to change even if a newer version of the .xz file format is developed in future.
|
extern |
Encode Stream Header.
| options | Stream Header options to be encoded. options->backward_size is ignored and doesn't need to be initialized. | |
| [out] | out | Beginning of the output buffer of LZMA_STREAM_HEADER_SIZE bytes. |
|
extern |
Encode Stream Footer.
| options | Stream Footer options to be encoded. | |
| [out] | out | Beginning of the output buffer of LZMA_STREAM_HEADER_SIZE bytes. |
|
extern |
Decode Stream Header.
options->backward_size is always set to LZMA_VLI_UNKNOWN. This is to help comparing Stream Flags from Stream Header and Stream Footer with lzma_stream_flags_compare().
| [out] | options | Target for the decoded Stream Header options. |
| in | Beginning of the input buffer of LZMA_STREAM_HEADER_SIZE bytes. |
|
extern |
Decode Stream Footer.
| [out] | options | Target for the decoded Stream Footer options. |
| in | Beginning of the input buffer of LZMA_STREAM_HEADER_SIZE bytes. |
|
extern |
Compare two lzma_stream_flags structures.
backward_size values are compared only if both are not LZMA_VLI_UNKNOWN.
| a | Pointer to lzma_stream_flags structure |
| b | Pointer to lzma_stream_flags structure |
