# rte\_comp\_decompress\_xform(3)

## NAME

rte\_comp\_decompress\_xform

## SYNOPSIS

`#include <rte_comp.h>`

### Data Fields

enum **rte\_comp\_algorithm** **algo**\
 enum **rte\_comp\_checksum\_type** **chksum**\
 uint8\_t **window\_size**\
 union {\
    struct **rte\_comp\_lz4\_params** **lz4**\
 }; \
 enum **rte\_comp\_hash\_algorithm** **hash\_algo**\

## Detailed Description

Setup Data for decompression.

Definition at line **312** of file **rte\_comp.h**.

## Field Documentation

### enum rte\_comp\_algorithm algo

Algorithm to use for decompression

Definition at line **313** of file **rte\_comp.h**.

### enum rte\_comp\_checksum\_type chksum

Type of checksum to generate on the decompressed data

Definition at line **315** of file **rte\_comp.h**.

### uint8\_t window\_size

Base two log value of sliding window which was used to generate compressed data. If window size can't be supported by the PMD then setup of stream or private\_xform should fail.

Definition at line **317** of file **rte\_comp.h**.

### struct rte\_comp\_lz4\_params lz4

Parameters specific to the LZ4 algorithm

Definition at line **323** of file **rte\_comp.h**.

### union { ... }

Algorithm specific parameters

### enum rte\_comp\_hash\_algorithm hash\_algo

Hash algorithm to be used with decompress operation. Hash is always done on plaintext.

Definition at line **326** of file **rte\_comp.h**.
