t,t

...
use winapi::minwindef::{LPVOID, DWORD, PDWORD};

fn main() {
    let address = 0xDEADBEEF; // in practice i know the address is right ok, just trust me.
    let old_protect: DWORD = 0;
    let t = unsafe { kernel32::VirtualProtect(address as LPVOID, 1, 0x40, old_protect as PDWORD) };
    println!("results: {}, {}", old_protect, t); // "t" returns 0, but I don't know why t.t
}

/*
I'm suspecting something is wrong with how I did things regarding old_protect.
I know that address is valid (checked it multiple times!) and that the other args (1, 0x40) are valid as I have equivalent C++ code that works fine.
VirtualProtect returns 0 when it fails - GetLastError() tells me the error is 0x3E6, which is ERROR_NOACCESS "Invalid access to memory location."
VirtualProtect takes (LPVOID, DWORD, DWORD, PDWORD),
LPVOID = *mut std::os::raw::c_void
DWORD = u32
PDWORD = *mut u32

I have no idea how to fix this :/
