Function close_handle

dumpy/dinvoke/src/lib.rs:385–419

Closes a HANDLE object. It will return either a boolean value or an Err with a descriptive error message. If the function fails the bool value returned will be false. # Examples ``` let pid = 792u32; let handle = dinvoke::open_process(0x0040, 0, pid).unwrap(); //PROCESS_DUP_HANDLE access right. if handle.0 != 0 && handle.0 != -1 { let r = dinvoke::close_handle(handle).unwrap(); if r { println!
