Parameters
- pCtx
- Pointer to theIppsSHA1Statecontext.
- pBuffer
- Pointer to the user-defined buffer.
Description
The
SHA1Pack
function transforms the *pCtx
context to a position-independent form and stores it in the *pBuffer
buffer. The SHA1Unpack
function performs the inverse operation, that is, transforms the contents of the *pBuffer
buffer into a normal IppsSHA1State
context. The SHA1Pack
and SHA1Unpack
functions enable replacing the position-dependent IppsSHA1State
context in the memory. 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 isNULL.
- ippStsContextMatchErr
- Indicates an error condition if the context parameter does not match the operation.
