SHA384Pack, SHA384Unpack
Packs/unpacks the IppsSHA384State context into/from a user-defined buffer.
Syntax
IppStatus ippsSHA384Pack (const IppsSHA384State* pCtx, Ipp8u* pBuffer);
IppStatus ippsSHA384Unpack (const Ipp8u* pBuffer, IppsSHA384State* pCtx);
Include Files
ippcp.h
Parameters
pCtx |
Pointer to the IppsSHA384State context. |
pBuffer |
Pointer to the user-defined buffer. |
Description
The SHA384Pack function transforms the *pCtx context to a position-independent form and stores it in the *pBuffer buffer. The SHA384Unpack function performs the inverse operation, that is, transforms the contents of the *pBuffer buffer into a normal IppsSHA384State context. The SHA384Pack and SHA384Unpack functions enable replacing the position-dependent IppsSHA384State context in the memory.
Call the SHA384GetSize function prior to SHA384Pack/SHA384Unpack 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. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
