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

\manname{MPID{\tt \char`\_}Err{\tt \char`\_}add{\tt \char`\_}class}
--- Add an error class with an associated string 
\subhead{Synopsis}
\startvb\begin{verbatim}
int MPID_Err_add_class( const char *msg_string, 
                      const char *instance_msg_string )

\end{verbatim}
\endvb

\subhead{Input Parameters}
\startarg{msg{\tt \char`\_}string }{Message text for this class.  A null string may be used, in
which case {\tt MPID{\tt \char`\_}Err{\tt \char`\_}set{\tt \char`\_}msg} should be called later.
}
\startarg{instance{\tt \char`\_}msg{\tt \char`\_}string }{Instance-specific message string.  See the error 
reporting overview.  May be the null string.
}
\par
\subhead{Return value}
An error class.
\par
\subhead{Notes}
This is used to implement {\tt MPI{\tt \char`\_}Add{\tt \char`\_}error{\tt \char`\_}class}; it may also be used by a
device to add device-specific error classes.  Unlike the MPI version, this
combines returning a class with setting the associated message.
\par
Predefined classes are handled directly; this routine is not used to
initialize the predefined MPI error classes.  This is done to reduce the
number of steps that must be executed when starting an MPI program.
\par
\subhead{Module}
Error
