Remarks

This writes a fresh set of random data to the seed file. The seed file must be writable by the user. Use this function at periodic intervals or when exiting your application. If the file does not exist it will be created. Any existing file of the same name will be overwritten without warning.

See the example in RNG_Initialize.
