Rijndael192Pack, Rijndael192Unpack

Packs/unpacks the IppsRijndael192Spec context into/from a user-defined buffer.

Syntax

IppStatus ippsRijndael192Pack (const IppsRijndael192Spec* pCtx, Ipp8u* pBuffer);

IppStatus ippsRijndael192Unpack (const Ipp8u* pBuffer, IppsRijndael192Spec* pCtx);

Parameters

pCtx	Pointer to the IppsRijndael192Spec context.
pBuffer	Pointer to the user-defined buffer.

Description

This functions are declared in the ippcp.h file. The Rijndael192Pack function transforms the *pCtx context to a position-independent form and stores it in the *pBuffer buffer. The Rijndael192Unpack function performs the inverse operation, that is, transforms the contents of the *pBuffer buffer into a normal IppsRijndael192Spec context. The Rijndael192Pack and Rijndael192Unpack functions enable replacing the position-dependent IppsRijndael192Spec context in the memory.

Call the Rijndael192GetSize function prior to Rijndael192Pack/Rijndael192Unpack to determine the size of the buffer.

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.
