Functions

win32 exposes the Win32 functions as global Dart functions, allowing you to call them just like any other Dart function. To maintain consistency with the C-based functions they wrap, these functions are named with TitleCase rather than Dart’s camelCase convention.

Detecting Success or Failure of a Function Call​

Most Win32 functions use the return value to indicate successful execution, with a non-zero value indicating success and zero indicating failure.

win32 provides SUCCEEDED() and FAILED() functions as convenient ways to test the result.

Here’s an example:

final hr = CloseWindow(hWnd); // minimizes a window with the given handle.
if (FAILED(hr)) {
  print('Window could not be minimized.');
}
