Executing a program from within another program

I am currently working in a group on a school project to create a Real Time Strategy game. I am trying to execute a game server program when one of the client's decides to 'Host' a game.

I am using the spawnl function. The problem is that the newly executed program runs in the same console program as the test client. The real client will be a Win32 app, so I don't know if it is truley an issue yet or not. But I would like to be able to separate my client and server into different console windows. Anyone have any ideas?

Code:

 spawnl(P_NOWAIT, "ServerMain.exe", "ServerMain.exe", strMapFilePath, iMaxPlayers, NULL );

iMaxPlayers is being used as a string, so no issues there.

Here is a windows function to suit your needs. It is based on code from FAQ: How do I run a program from within a program.

Code:

#include <windows.h>
#include <cstdio>
using namespace std;

BOOL SpawnInNewConsole(LPCTSTR szPath)
{
  STARTUPINFO si = { 0 };     // Defines how to start the program
  PROCESS_INFORMATION pi;     // Gives info on the thread and..
                              // ..process for the new process

  si.cb = sizeof(si);         // Must set size of structure

  BOOL bRet = CreateProcess(
        szPath, // Path to executable file
        NULL,   // Command string - not needed here
        NULL,   // Process handle not inherited
        NULL,   // Thread handle not inherited
        FALSE,  // No inheritance of handles
        CREATE_NEW_CONSOLE,   // Create a new console for program
        NULL,   // Same environment block as this prog
        NULL,   // Current directory - no separate path
        &si,    // Pointer to STARTUPINFO
        &pi);   // Pointer to PROCESS_INFORMATION

  if(bRet)
  {
    CloseHandle(pi.hThread);    // Close handle to thread
    CloseHandle(pi.hProcess);   // Close handle to process
  }

  return bRet;
}

int main(void)
{
  if (!SpawnInNewConsole("ServerMain.exe"))
  {
    printf("Failed to launch program!");
  }

  return 0;
}

Okay, so for the command string, would I seperate the things I need to send into it with spaces, or how does it delimit multiple strings that need to be sent in? My executable program requires argv[] for how it is initialized. I need to send both strMapFilePath and iMaxPlayers into it upon initialization.
