Comment(by nickm):

 Also see http://www.dwheeler.com/secure-programs/Secure-Programs-HOWTO
 /protect-secrets.html :
 {{{
  void *guaranteed_memset(void *v,int c,size_t n)
   { volatile char *p=v; while (n--) *p++=c; return v; }
 }}}
 (Totally untested on modern compilers; the advice at the end of that page
 makes me think that the document could be a bit dated.)
