Parameters
- pSeed
- Pointer to the seed value being set up.
- pCtx
- Pointer to theIppsPRNGStatecontext.
Description
The function resets the seed value with the supplied value of
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.
This function restarts the pseudorandom number generation process, which results in losing already generated pseudorandom numbers.
