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

       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.
