I'm electron spawn a C language program in the program as a child, how can I communicate with t-CodePudding

C language code is:

 
#include  
Int main () {
int i=0; 
The scanf (" % d ", & amp; I); 
Printf (" % d \ n ", I); 
The scanf (" % d ", & amp; I); 
Printf (" % d \ n ", I); 
return 0; 
}

I use sub_process. Stdin. Write (" 1 \ n "); Later, it will not immediately output;
When I use it twice program_process. Stdin. Write (" 1 \ n "); It will all output two 1;
But I hope to enter a program_process. Stdin. Write (" 1 \ n "); It's
Sub_process. Stdout. On (' data '(data)=& gt; {the console. The log (data); });
Will output a 1, as the program logic, but the reality is not, you only have two consecutive input 1, it can output two consecutive 1, this should be the problem of buffer transfer, I don't know exactly what is going on,

Some people say that to do so:

 
Sub_process. Stdin. Lawsuits (); 
Sub_process. Stdin. Write (" 1 \ n "); 
Sub_process. Stdin. Uncork ();

But I tried it on and I can't, or asynchronous:

 
Sub_process. Stdin. Lawsuits (); 
Sub_process. Stdin. Write (" 1 \ n ", function () {sub_process. Stdin. Uncork (); });

They don't even output, output
