Same variable names in different level2 s-functions or multiple instances of same level2 s-function will be stored separately?

Hi,

I am writing level 2 s functions for c code and I am using the same s function multiple instances or I will make different named s-functions with the same code. I am defining variables inside the s-functions with same name (Like i,j). The variables values will be different for different s-functions or each instance of s-function. Will there be any conflict between variables since it is with same name in multiple s-functions or will it be treated as diffrent varaibles?

% s-function1 code%

#define S_FUNCTION_NAME test

#define S_FUNCTION_LEVEL 2

#include "simstruc.h"

float i=0,j=0;

static void mdlInitializeSizes(SimStruct *S)

{

....

%s-function2 code%

#define S_FUNCTION_NAME test1

#define S_FUNCTION_LEVEL 2

#include "simstruc.h"

float i=0,j=0;

static void mdlInitializeSizes(SimStruct *S)

{

....

Thanks,
