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