I am trying to compile my originally visual c++ project on Xcode so I can run it on macOSX and as I can't use windows.h in Xcode/mac I'm looking for alternatives.
Could you give me some ways to replace these subroutines:
UINT SendString(string str)
   UINT count = 0;
   for (size_t i = 0; i < str.size();i++)
      INPUT input[2];
      ::ZeroMemory(input, sizeof(input)); 
      input[0].type = input[1].type = INPUT_KEYBOARD;
      input[0].ki.wVk  = input[1].ki.wVk = VkKeyScan(str[i]);
      input[1].ki.dwFlags = KEYEVENTF_KEYUP;
      count += SendInput(2, input, sizeof(INPUT));
   return count;
void SendKey(char key){
void MouseMove(int x, int y )
	double fScreenWidth    = ::GetSystemMetrics( SM_CXSCREEN )-1; 
	double fScreenHeight  = ::GetSystemMetrics( SM_CYSCREEN )-1; 
	double fx = x*(65535.0f/fScreenWidth);
	double fy = y*(65535.0f/fScreenHeight);
	INPUT  Input={0};
	Input.type      = INPUT_MOUSE;
	Input.mi.dx = fx;
	Input.mi.dy = fy;
void MouseClick(string button, string mode){
	INPUT    Input={0};
	Input.type = INPUT_MOUSE;
	if(mode == "down"){
		if(button == "left"){Input.mi.dwFlags=MOUSEEVENTF_LEFTDOWN;}else if(button == "right"){Input.mi.dwFlags=MOUSEEVENTF_RIGHTDOWN;}
	}else if(mode == "up"){
		if(button=="left"){Input.mi.dwFlags=MOUSEEVENTF_LEFTUP;}else if(button=="right"){Input.mi.dwFlags=MOUSEEVENTF_RIGHTUP;}
	}else if(mode == "both"){
		if(button == "left"){Input.mi.dwFlags=MOUSEEVENTF_LEFTDOWN;}else if(button == "right"){Input.mi.dwFlags=MOUSEEVENTF_RIGHTDOWN;}
		if(button=="left"){Input.mi.dwFlags=MOUSEEVENTF_LEFTUP;}else if(button=="right"){Input.mi.dwFlags=MOUSEEVENTF_RIGHTUP;}

ShellExecute(NULL, L"open", L"", NULL, NULL, SW_SHOWNORMAL);

What's the platform? Tag it. What's the problem? Having declarations from Windows API? You can replace some of them, such as UINT, not those which are Windows-specific...
Jochen Arndt 13-Dec-12 3:08am
You should rephrase your question. I assume you mean something like 'How to convert this Windows code to OS X / iOS using Xcode'.
But there is no simple conversion. You probably must write new code that does the the same tasks using the OS X API. I never wrote programs for OS X / iOS but I'm quite sure that there are no direct replacement functions for SendInput() and ShellExecute().

Maybe not iOS, but Linux?
Jochen Arndt 13-Dec-12 5:02am
Using Xcode to develop Linux applications seems to be an advanced task. I assume OS X, eventually iOS. But only the questioner knows.
Jochen Arndt 13-Dec-12 8:39am
With the updated question it is now clear what you want. But I already gave you the answer:
You must find OS X API functions that perform the required tasks. For keyboard events (simulating key press events), this might be CGEventCreateKeyboardEvent() and CGEventPost().

The OS X and Windows API are totally different. So you must write completely new code.

Ok, thanks

Maybe post this as solution... otherwise it stays as unanswered.

+5, supporting multiple platforms after the fact is always a pain (i.e. not programming for it in advance)

Thank you.
