:ref:`MPI_Session_get_pset_info` is used to query properties of a specific process set. The returned info object can be queried with existing MPI info object query functions. One key/value pair must be defined, "mpi_size". The value of the "mpi_size" key specifies the number of MPI processes in the process set.
The user is responsible for freeing the returned info object via :ref:`MPI_Info_free`.
