Parameters
- pIV
- Pointer to the initialization vector.
- ivLen
- Length of the initialization vector*pIV(in bytes).
- pAAD
- Pointer to the additional authenticated data.
- aadLen
- Length of additional authenticated data*pAAD(in bytes).

Description
The function resets internal counters and buffers of the *
pState
context. Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or warning.
- ippStsNullPtrErr
- Indicates an error condition if any of the specified pointers is NULL.
- ippStsContextMatchErr
- Indicates an error condition if the context parameter does not match the operation.
- ippStsLengthErr
- Indicates an error condition if the length of the initialization vector is zero.
