dtfft_get_local_sizes_c Function

private function dtfft_get_local_sizes_c(plan_ptr, in_starts, in_counts, out_starts, out_counts, alloc_size) result(error_code) bind(C)

Returns local sizes, counts in real and Fourier spaces and number of elements to be allocated for in and out buffers, C/C++ interface.

Arguments

Type IntentOptional Attributes Name
type(c_ptr), value :: plan_ptr

C pointer to Fortran plan
integer(kind=c_int32_t), intent(out), optional :: in_starts(3)

Starts of local portion of data in ‘real’ space
integer(kind=c_int32_t), intent(out), optional :: in_counts(3)

Counts of local portion of data in ‘real’ space
integer(kind=c_int32_t), intent(out), optional :: out_starts(3)

Starts of local portion of data in ‘fourier’ space
integer(kind=c_int32_t), intent(out), optional :: out_counts(3)

Counts of local portion of data in ‘fourier’ space
integer(kind=c_size_t), intent(out), optional :: alloc_size

Minimum data needs to be allocated

Return Value integer(kind=c_int32_t)

The enumerated type dtfft_error_t defines API call result codes.
