RtlRandom function

The RtlRandom routine returns a random number that was generated from a given seed value.

Syntax

NTSYSAPI ULONG RtlRandom(
  PULONG Seed
);

Parameters

Seed

Unsigned long value from which to generate a random number.

Return Value

RtlRandom returns a random number in the range [0..MAXLONG-1].

Remarks

RtlRandom 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 that is twice as fast and produces better random numbers.
