5.7 'acc_async_test' - Test for completion of a specific asynchronous operation.
================================================================================

_Description_
     This function tests for completion of the asynchronous operation
     specified in ARG.  In C/C++, a non-zero value will be returned to
     indicate the specified asynchronous operation has completed.  While
     Fortran will return a 'true'.  If the asynchronous operation has
     not completed, C/C++ returns a zero and Fortran returns a 'false'.

_C/C++_:
     _Prototype_:   'int acc_async_test(int arg);'

_Fortran_:
     _Interface_:   'function acc_async_test(arg)'
                    'integer(kind=acc_handle_kind) arg'
                    'logical acc_async_test'
