Function load_library_a

dumpy/dinvoke/src/lib.rs:282–314

Loads and retrieves a module's base address by dynamically calling LoadLibraryA. It will return either the module's base address or an Err with a descriptive error message. # Examples ``` let ret = dinvoke::load_library_a("ntdll.dll"); match ret { Ok(addr) => if addr != 0 {println!("ntdll.dll base address is 0x{:X}.", addr)}, Err(e) => println!("{}",e), } ```
