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 error handler function 
\subhead{Synopsis}
\startvb\begin{verbatim}
typedef union {
   void (*C_Comm_Handler_function) ( MPI_Comm *, int *, ... );
   void (*F77_Handler_function) ( MPI_Fint *, MPI_Fint *, ... );
   void (*C_Win_Handler_function) ( MPI_Win *, int *, ... );
   void (*C_File_Handler_function) ( MPI_File *, int *, ... );
} MPID_Errhandler_fn;

\end{verbatim}
\endvb

\subhead{Notes}
The MPI-1 Standard declared only the C version of this, implicitly
assuming that {\tt int} and {\tt MPI{\tt \char`\_}Fint} were the same.

\subhead{Questions}
What do we want to do about C++?  Do we want a hook for a routine that can
be called to throw an exception in C++, particularly if we give C++ access
to this structure?  Does the C++ handler need to be different (not part
of the union)?
\par
What is the interface for the Fortran version of the error handler?
