MD5Update
Digests the current input message stream of the specified length (deprecated).
Syntax
IppStatus ippsMD5Update(const Ipp8u *pSrc, int len, IppsMD5State *pCtx);
Include Files
ippcp.h
Parameters
pSrc |
Pointer to the buffer containing a part of or the whole message. |
len |
Length of the actual part of the message in bytes. |
pCtx |
Pointer to the IppsMD5State context. |
Description
The function digests the current input message stream of the specified length.
The function first integrates the previous partial block with the input message stream and then partitions them into multiple message blocks (as specified by the applied hash algorithm) with a possible additional partial block. For each message block, the function uses the selected hash algorithm to transform the block into a new chaining digest value.
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. |
ippStsLengthErr |
Indicates an error condition if the input data stream length is less than zero. |
