MD5Pack, MD5Unpack
Packs/unpacks the IppsMD5State context into/from a user-defined buffer (deprecated).
Syntax
IppStatus ippsMD5Pack (const IppsMD5State* pCtx, Ipp8u* pBuffer);
IppStatus ippsMD5Unpack (const Ipp8u* pBuffer, IppsMD5State* pCtx);
Include Files
ippcp.h
Parameters
pCtx |
Pointer to the IppsMD5State context. |
pBuffer |
Pointer to the user-defined buffer. |
Description
The MD5Pack function transforms the *pCtx context to a position-independent form and stores it in the *pBuffer buffer. The MD5Unpack function performs the inverse operation, that is, transforms the contents of the *pBuffer buffer into a normal IppsMD5State context. The MD5Pack and MD5Unpack functions enable replacing the position-dependent IppsMD5State context in the memory.
Call the MD5GetSize function prior to MD5Pack/MD5Unpack 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. |
