  • This getauxval wrapper allows to query the auxiliary vector for both Linux and FreeBSD.
  • Other libraries tend to do the same like here.
  • Tested with the following `const std = @import("std");

pub fn main() !void { const key: u32 = std.c.AT.EXECPATH; var r = try std.os.getauxval(key); std.debug.print("{}\n", .{@intToPtr(*const u8, r)}); }`
