刚才是说明 现在是安装程序在 LINUX环境下进行编程的MPICH安装文件

--- MPID Structure to hold an attribute copy function 
\subhead{Synopsis}
\startvb\begin{verbatim}
typedef union {
  MPI_Comm_copy_attr_function *C_CommCopyFunction;
  MPI_Win_copy_attr_function  *C_WinCopyFunction;
  MPI_Type_copy_attr_function *C_TypeCopyFunction;
  void (*F77_CopyFunction)  ( MPI_Fint *, MPI_Fint *, MPI_Fint *, MPI_Fint *, 
                            MPI_Fint *, MPI_Fint *, MPI_Fint * );
  void (*F90_CopyFunction)  ( MPI_Fint *, MPI_Fint *, MPI_Aint *, MPI_Aint *,
                            MPI_Aint *, MPI_Fint *, MPI_Fint * );
  /* The C++ function is the same as the C function */
} MPID_Copy_function;

\end{verbatim}
\endvb

\subhead{Notes}
The appropriate element of this union is selected by using the language
field of the {\tt keyval}.
\par
The function types used in the union are provided by {\tt mpi.h}.  The
correspond to:
\begin{verbatim}
  int  (*C_CommCopyFunction)( MPI_Comm, int, void *, void *, void *, int * );
  int (*C_WinCopyFunction) ( MPI_Win, int, void *, void *, void *, int * );
  int (*C_TypeCopyFunction) ( MPI_Datatype, int, 
                            void *, void *, void *, int * );
\end{verbatim}

There are no corresponding typedefs for the Fortran functions.  The
F77 function corresponds to the Fortran 77 binding used in MPI-1 and the
F90 function corresponds to the Fortran 90 binding used in MPI-2.
\par
\subhead{Question}
Do we want to create typedefs for the two Fortran functions?

\subhead{Module}
