# rte\_event\_crypto\_metadata(3)

## NAME

rte\_event\_crypto\_metadata

## SYNOPSIS

`#include <rte_event_crypto_adapter.h>`

### Data Fields

struct **rte\_event\_crypto\_request** **request\_info**\
 struct **rte\_event** **response\_info**\

## Detailed Description

Crypto event metadata structure will be filled by application to provide crypto request and event response information.

If crypto events are enqueued using a HW mechanism, the cryptodev PMD will use the event response information to set up the event that is enqueued back to eventdev after completion of the crypto operation. If the transfer is done by SW, event response information will be used by the adapter.
