Struct dlopen::raw::AddressInfoObtainer

pub struct AddressInfoObtainer {}

Obtains information about an address previously loaded from a dynamic load library.

Methods

impl AddressInfoObtainer

pub fn new() -> AddressInfoObtainer

pub fn obtain(&self, addr: *const ()) -> Result<AddressInfo, Error>

Obtains information about an address previously loaded from a dynamic load library.

Example

extern crate dlopen;
use dlopen::raw::{Library, AddressInfoObtainer};
fn main() {
    let lib = Library::open("libyourlib.so").unwrap();
    let ptr: * const i32 = unsafe{ lib.symbol("symbolname") }.unwrap();

    // now we can obtain information about the symbol - library, base address etc.
    let aio = AddressInfoObtainer::new();
    let addr_info = aio.obtain(ptr as * const ()).unwrap();
    println!("Library path: {}", &addr_info.dll_path);
    println!("Library base address: {:?}", addr_info.dll_base_addr);
    if let Some(os) = addr_info.overlapping_symbol{
        println!("Overlapping symbol name: {}", &os.name);
        println!("Overlapping symbol address: {:?}", os.addr);
    }

}
