See this link.

Thanks alot I will try figure them out. :cool:

Those functions are not so simple, so maybe this:

Code:

---

#include <stdio.h>
...
FILE *f = fopen("filepath","r+");
//write a char
putc(char,f)
//get a char
int char = getc(f);

---

The code might be long, but they are more suitable for a Windows environment.
