NAME

       MPI_T_pvar_get_num -  Get the number of performance variables

SYNOPSIS

       int MPI_T_pvar_get_num(int *num_pvar)

OUTPUT PARAMETERS

       num_pvar
              - returns number of performance variables (integer)

THREAD AND INTERRUPT SAFETY

       This routine is thread-safe.  This means that this routine may be safely used by multiple threads without
       the need for any user-provided thread locks.  However, the routine is  not  interrupt  safe.   Typically,
       this  is  due to the use of memory allocation routines such as malloc or other non-MPICH runtime routines
       that are themselves not interrupt-safe.

ERRORS

       All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of  the
       function  and Fortran routines in the last argument.  Before the value is returned, the current MPI error
       handler is called.  By default, this error handler aborts the MPI job.  The error handler may be  changed
       with    MPI_Comm_set_errhandler   (for   communicators),   MPI_File_set_errhandler   (for   files),   and
       MPI_Win_set_errhandler (for RMA windows).  The MPI-1 routine MPI_Errhandler_set may be used but  its  use
       is  deprecated.   The  predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be
       returned.  Note that MPI does not guarantee that an MPI program can continue past an error; however,  MPI
       implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_T_ERR_INVALID
              - Invalid use of the interface or bad parameter values(s).
       MPI_T_ERR_NOT_INITIALIZED
              - The MPI tool information interface is not initialized.
       MPI_ERR_OTHER
              - Other error; use MPI_Error_string to get more information about this error code.
