这样定义为什么不对呢?执行时总是出错,提示说: "run-time check failure #3 - the variable 'si ' is being used without being defined. "
lpstartupinfoa si;
lpprocess_information pi;
memset（si,0,sizeof（si));
memset（pi,0,sizeof（pi));

si-> cb = sizeof（lpstartupinfoa);
getstartupinfoa（si);
si-> hstderror = hwrite;
si-> hstdoutput = hwrite;
// si.wshowwindow = sw_show;
// si.wshowwindow = sw_hide;
si-> dwflags = startf_useshowwindow ¦ startf_usestdhandles;

startupinfo si;
process_information pi;

zeromemory（ &si, sizeof（si) );
si.cb = sizeof（si);
zeromemory（ &pi, sizeof（pi) );

// start the child process.
if（ !createprocess（ null, // no module name （use command line).
text（ "mychildprocess "), // command line.
null, // process handle not inheritable.
null, // thread handle not inheritable.
false, // set handle inheritance to false.
0, // no creation flags.
null, // use parent 's environment block.
null, // use parent 's starting directory.
&si, // pointer to startupinfo structure.
&pi ) // pointer to process_information structure.
)
{
printf（ "createprocess failed （%d).\n ", getlasterror（) );
return;
}

不要定义指针。
