| IN sendbuf | starting address of send buffer (choice) |

| IN recvcounts | non-negative integer array specifying the number of elements in result distributed to each process. Array must be identical on all calling processes. |
| IN datatype | data type of elements of input buffer (handle) |
| IN op | operation (handle) |
| IN comm | communicator (handle) |
| OUT request | communication request (handle) |
