Skipping Over a Function

matorin57 (14)
So I am using SDL and I am refrencing a function that renders a image. But when I run the program it skips over the function and I am completely lost. I am using Visual 2010 and Any help would be greatly appreciated

here is main.cpp the main file

using namespace std;
#include <SDL.h>
#include <string>
#include <fstream>
#include <conio.h>
#include "Screen_Global.h"
#include "Render.h"
#include "inti.h"
//map index 
int mapIndex = 0;
int main( int argc, char* args[] )
{
	//intitilize SDL
	if(init() == false)
	{
		return 1;
	}
	// quitting enabler
	bool quit = false;
	//main loop
	while(quit==false)
	{
		//rending function
		rendUpdate(mapIndex);
		//debug point
		system("pause");
		break;
	}
	return 0;
}


And here is the file function that renders

#include <SDL.h>
#include "Render.h"
#include "Screen_Global.h"
using namespace std;
void rendUpdate(int mapIndex)
{
	if(mapIndex = 0)
	{
		SDL_Surface *message = NULL;
		message = load_image("\\image\\text.bmp");
		apply_surface(0, 0, message, screen);
	}
	else if(mapIndex = 1)
	{
	}
}


And here is its header

using namespace std;
#include <SDL.h>
#include <string>
void rendUpdate(int mapindex);
void apply_surface(int x, int y, SDL_Surface* source, SDL_Surface* destination);
SDL_Surface *load_image(string filename);

if(mapIndex = 0)That's assignment, not comparison.

Don't put using namespace std; in headers, it's dangerous.
Use headers guards.
