- Pointer to theIppsARCFourStatecontext.
- pBuffer
- Pointer to the user-defined buffer.
Description
These functions are deprecated.
The
ARCFourPack
function transforms the *pCtx
context to a position-independent form and stores it in the *pBuffer
buffer. The ARCFourUnpack
function performs the inverse operation, that is, transforms the contents of the *pBuffer
buffer into a normal IppsARCFourState
context. The ARCFourPack
and ARCFourUnpack
functions enable replacing the position-dependent IppsARCFourState
context in the memory. Call the
ARCFourGetSize
function prior to ARCFourPack
/ARCFourUnpack
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 isNULL.
