title: Does sscanf modify the string passed to it?
body: <p>Can I know if sscanf modifies the string passed to it. Or can anybody please point me where I can find the source code for sscanf ? </p>
  
  <p>I downloaded glibc and found the following :</p>
  
  <pre><code>extern int sscanf (__const char *__restrict __s,
                 __const char *__restrict __format, ...) __THROW;
  extern int sscanf (__const char *__restrict __s,
                 __const char *__restrict __format, ...) __THROW;
  </code></pre>
