DLPPack, DLPUnpack

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

Syntax

IppStatus ippsDLPPack (const IppsDLPState* pCtx, Ipp8u* pBuffer);

IppStatus ippsDLPUnpack (const Ipp8u* pBuffer, IppsDLPState* pCtx);

Parameters

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

Description

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

Call the DLPGetSize function prior to DLPPack/DLPUnpack 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.
