- 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.
- ippStsLengthErr
- Indicates an error condition ifmdLenis less than one or greater than the length of the hash value.
