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
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. |
