SYNTAX
   C Syntax
          #include <mpi.h>

          int MPI_T_pvar_session_create(MPI_T_pvar_session *session)

          int MPI_T_pvar_session_free(MPI_T_pvar_session *session)


DESCRIPTION
       MPI_T_pvar_session_create  creates  a  session  for  accessing  performance variables. The new session is
       returned in the session parameter.

       MPI_T_pvar_session_free releases a session allocated by MPI_T_pvar_session_create and  sets  the  session
       parameter to MPI_T_PVAR_SESSION_NULL.
