ARCFourPack, ARCFourUnpack

Packs/unpacks the IppsARCFourSpec context into/from a user-defined buffer (deprecated).

Syntax

IppStatus ippsARCFourPack (const IppsARCFourState* pCtx, Ipp8u* pBuffer);

IppStatus ippsARCFourUnpack (const Ipp8u* pBuffer, IppsARCFourState* pCtx);

Include Files

ippcp.h

Parameters

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

Description

Note

These functions are deprecated.

The ARCFourPack function transforms the *pCtx context to a position-independent form and stores it in the *pBuffer buffer. The ARCFourUnpack function performs the inverse operation, that is, transforms the contents of the *pBuffer buffer into a normal IppsARCFourState context. The ARCFourPack and ARCFourUnpack functions enable replacing the position-dependent IppsARCFourState context in the memory.

Call the ARCFourGetSize function prior to ARCFourPack/ARCFourUnpack 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.
