Function multiboot2::load_with_offset

pub unsafe fn load_with_offset(
    address: usize, 
    offset: usize
) -> Result<BootInformation, MbiLoadError>

Load the multiboot boot information struct from an address at an offset.

Example

use multiboot2::load_with_offset;

let ptr = 0xDEADBEEF as *const u32;
let boot_info = unsafe { load_with_offset(ptr as usize, 0xCAFEBABE).unwrap() };
println!("{:?}", boot_info);

Safety

• address must be valid for reading. Otherwise this function might terminate the program. This can be the case in environments with standard environment (segfault) but also in UEFI-applications, where the referenced memory is not (identity) mapped (UEFI does only identity mapping).
• The memory at address must not be modified after calling load or the program may observe unsychronized mutation.
