NAME
RtlUniform (NTDLL.@)
SYNOPSIS
ULONG RtlUniform
(
PULONG seed
)
DESCRIPTION
Generates an uniform random number.
PARAMS
seed [Out] The seed of the Random function.
RETURNS
It returns a random number uniformly distributed over [0..MAXLONG-1].
NOTES
Generates an uniform random number using D.H. Lehmer's 1948 algorithm. In our case the algorithm is:
result = (*seed * 0x7fffffed + 0x7fffffc3) % MAXLONG;
*seed = result;.
DIFFERENCES
The native documentation states that the random number is uniformly distributed over [0..MAXLONG]. In reality the native function and our function return a random number uniformly distributed over [0..MAXLONG-1].
IMPLEMENTATION
Declared in "winternl.h".
Implemented in "dlls/ntdll/rtl.c".
Debug channel "ntdll".
