title: static and inline
body: <p>Iam programing in C. I want some description about static and inline functions. I know that if we make a function static then it is an indication to compiler that it is under internal linkage for only one translation unit. 
  I have following doubts regarding static and inline :</p>
  
  <ol>
  <li>If we make a function as static , can we use it in other translation units ...i.e in other .c files? If yes ..how?</li>
  <li>If we make the function as static inline what is the difference then ? How it will be treated by the compiler ? </li>
  <li>Does making a function as static gives the same effect as a macro? </li>
  <li>Treating a function to be inline is dependent on the compiler depending on the size . So is there any way that we can forcefully make it to be  treated like inline?</li>
  <li>How we can use inline and static functions for optimization ?</li>
  </ol>
  
  <p>Please shed some light on the above things inline.
  Platform is Linux, gcc compiler , C language.</p>
