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.

       o MPI_T_ERR_NOT_INITIALIZED: The MPI Tools interface not initialized

       o MPI_T_ERR_MEMORY: Out of memory

       o MPI_T_ERR_OUT_OF_SESSIONS: No more sessions available

       MPI_T_pvar_session_free will fail if:

       o MPI_T_ERR_NOT_INITIALIZED: The MPI Tools interface not initialized
