+/// The InitializeObjectAttributes macro initializes the opaque OBJECT_ATTRIBUTES structure,
+/// which specifies the properties of an object handle to routines that open handles.
+///
+/// # Parameters
+/// - `p`: A pointer to an OBJECT_ATTRIBUTES structure to be initialised (output).
+/// - `n`: A pointer to a UNICODE_STRING that specifies the object name (input).
+/// - `a`: The object attributes (input).
+/// - `r`: A pointer to the root directory (input).
+/// - `s`: A pointer to the security descriptor (input, optional).
+///
+/// # Returns
+/// This function returns:
+/// - `Ok(())` if the `POBJECT_ATTRIBUTES` pointer was valid, indicating
+/// the fields of the input OBJECT_ATTRIBUTES were assigned to.
+/// - `Err(())` if the `POBJECT_ATTRIBUTES` pointer was null.
+///
+/// # Safety
+/// This function accesses raw pointers and modifies memory. Ensure all pointers
+/// are valid before calling this function. The function will check for an invalid
+/// POBJECT_ATTRIBUTES before attempting to dereference it.
+/// 
+/// # Example
+/// ```
+/// // Define a UNICODE_STRING with the desired string
+/// let mut log_path_unicode = UNICODE_STRING::default();
+/// let src = "My Unicode string".encode_utf16().chain(once(0)).collect::<Vec<_>>();
+/// unsafe { RtlInitUnicodeString(&mut log_path_unicode, src.as_ptr()) };
+/// 
+/// // Prepare the OBJECT_ATTRIBUTES structure
+/// let mut oa: OBJECT_ATTRIBUTES = OBJECT_ATTRIBUTES::default();
+/// 
+/// // Initialise the OBJECT_ATTRIBUTES structure
+/// let result = unsafe {
+///     InitializeObjectAttributes(
+///         &mut oa,
+///         &mut log_path_unicode,
+///         OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE,
+///         null_mut(),
+///         null_mut(),      
+///     )
+/// };
+/// 
+/// // Handle the result
+/// match result {
+///     Ok(()) => println!("OBJECT_ATTRIBUTES initialized successfully"),
+///     Err(()) => eprintln!("Failed to initialize OBJECT_ATTRIBUTES"),
+/// }
