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{MPIU{\tt \char`\_}Malloc}
--- Allocate memory 
\subhead{Synopsis}
\startvb\begin{verbatim}
void *MPIU_Malloc( size_t len )

\end{verbatim}
\endvb

\subhead{Input Parameter}
\startarg{len }{Length of memory to allocate in bytes
}
\par
\subhead{Return Value}

\subhead{Notes}
This routine will often be implemented as the simple macro
\begin{verbatim}
  #define MPIU_Malloc(n) malloc(n)
\end{verbatim}

However, it can also be defined as
\begin{verbatim}
  #define MPIU_Malloc(n) MPIU_trmalloc(n,__FILE__,__LINE__)
\end{verbatim}

where {\tt MPIU{\tt \char`\_}trmalloc} is a tracing version of {\tt malloc} that is included with
MPICH.
