acc_async_test_all -- Tests for completion of all asynchronous operations.
**************************************************************************

Description
  This function tests for completion of all asynchronous operations.
  In C/C++, a non-zero value will be returned to indicate all asynchronous
  operations have completed. While Fortran will return a ``true``. If
  any asynchronous operation has not completed, C/C++ returns a zero and
  Fortran returns a ``false``.
