And with a coarray :


$ cat zz1.f90
program p
   use iso_c_binding, only: c_intptr_t
   integer, parameter :: omp_event_handle_kind =3D c_intptr_t
   integer (kind=3Domp_event_handle_kind) :: x[*]
   !$omp task detach (x)
   !$omp end task
end


$ cat zz2.f90
program p
   use iso_c_binding, only: c_intptr_t
   integer, parameter :: omp_event_handle_kind =3D c_intptr_t
   integer (kind=3Domp_event_handle_kind) :: x[*]
   !$omp parallel master default (none)
      !$omp task detach (x)
      !$omp end task
   !$omp end parallel master
end
