							 ^^^^^^
this statement increments fp2 to point to the next struct foo, not to the
next byte in struct foo as pointed to by fp2, as this example seems to
want. why not just use
 bzero((char *)fooptr, sizeof(struct foo))
to zero out the structure.  besides, what's wrong with calloc()? have I
missed some point you were trying to make here?
