The RtlRandomEx routine returns a random number that was generated from a given seed value.
NTSYSAPI ULONG RtlRandomEx( PULONG Seed );
Unsigned long value from which to generate a random number.
RtlRandomEx returns a random number in the range [0..MAXLONG-1].
RtlRandomEx returns values that are uniformly distributed over the range from zero to the maximum possible LONG value less 1 if it is called repeatedly with the same Seed.
The RtlRandomEx function is an improved version of the RtlRandom function. Compared with the RtlRandom function, RtlRandomEx is twice as fast and produces better random numbers since the period of the random numbers generated is comparatively higher.
