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);
Include Files
ippcp.h
Parameters
pCtx |
Pointer to the IppsDLPState context. |
pBuffer |
Pointer to the user-defined buffer. |
Description
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. |
