  • Implemented only to address the os.mincore wrapper.
  • Tested with the following
    `const std = @import("std");
    const os = std.os;

pub fn main() !void {
var p: [std.mem.page_size]u8 = undefined;
var pg = try os.mmap(null, std.mem.page_size, os.PROT.READ | os.PROT.WRITE, os.MAP.PRIVATE | os.MAP.ANONYMOUS, -1, 0);
defer os.munmap(pg);
try os.mincore(pg.ptr, std.mem.page_size / 2, &p);
}`
