c++ program ->i like to call a function of the same program but that has to be execute in background and also in a different process ID.

Ya exactly..

the create thread will execute the function in different thread in the same process. How i want is that the function has to be execute in the background in different process. Me attaching the code below.

In this program, the add() function will run in background process, after the completion of the whole function, the background process will be closed but the original process remains as it is... How to delete that process...


#include "stdafx.h"
#include <time.h>
#include <iostream>
#include <windows.h>
#include <stdlib.h>
using namespace std;


DWORD WINAPI add( LPVOID lpParameter)
{
int a,b,c;
cout<<"a:";
cin>>a;
cout<<endl;
cout<<"b:"<<endl;
cin>>b;
c=a+b;
cout<<"sum(c)="<<c<<endl;
return 0;
}

void wait ( int seconds )
{
clock_t endwait;
endwait = clock () + seconds * CLOCKS_PER_SEC ;
while (clock() < endwait){}
}

int main ()
{
DWORD dwThreadID;
int n,frequency;
HANDLE hProcess;
PROCESS_INFORMATION processInformation;
STARTUPINFO startupInfo;
cout<<"enter the frequency:";
cin>>frequency;
CreateProcess(TEXT("sameprocess.exe"), NULL, NULL, NULL, FALSE, HIGH_PRIORITY_CLASS|CREATE_NEW_CONSOLE, NULL, NULL, &startupInfo, &processInformation);
for(int i=0;i<2;i++)
{

HANDLE hThread = CreateThread(0,0,add,0,0,&dwThreadID);
cout<<"hi hello";
wait (frequency);
}
printf ("FIRE!!!\n");
//WaitForSingleObject( processInformation.hProcess, INFINITE );
CloseHandle( processInformation.hProcess );
CloseHandle( processInformation.hThread );
return 0;
}


And my program is not waiting for the user input , give me a solution for this..
