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.)
