pAugment
, IppsPRNGState*
pCtx
);

Parameters
- pAugment
- Pointer to the entropy augment value being set up.
- pCtx
- Pointer to theIppsPRNGStatecontext.
Description
The function resets entropy augment value with the supplied value of the
seedBits
bit length. The supplied big number should be created prior to the function call using the appropriate Big Number Arithmetic functions (see Example “Create a Big Number”
).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.
