H5FD_MPIO
driver, H5Pget_fapl_mpio
returns duplicates of
the stored MPI communicator and Info object through the
comm
and info
pointers, if those values are non-null.
Since the MPI communicator and Info object are duplicates of the stored information, future modifications to the access property list will not affect them. It is the responsibility of the application to free these objects.

IN: File access property list identifier |

Release | Change |
1.4.5 | Handling of the MPI Communicator and Info object changed at this release. A duplicate of each of these objects is now returned instead of pointers to each object. |
1.4.0 | C function introduced in this release. |
