Map Compatiblity
The map clause works with variables of various data types in both C/C++ and Fortran. The following data types are supported:
| Type | C/C++ | Fortran |
|---|---|---|
| scalars | int a; |
integer :: a |
| arrays | int a[8]; |
integer :: a(N) |
| pointers1 | int *ptr; |
integer, pointer :: a |
| structs / derived types | struct { ... } |
type :: ... |
| array sections | a[lower:length:stride] |
a(lower:upper:stride) |
1 Mapping a pointer in C/C++ is treated as if the base pointer of a zero-length array section is mapped by the map clause. To map the data that a pointer refers to, you must specify an array section.
Below is a simple example showing how scalars, arrays, and pointers are mapped.
