Hi,
In this snippet,
DH *dh;
if ((dh->g = BN_new()) == NULL)-------------> 1
goto end;
if (!BN_set_word(dh->g, g)) -----------------------> 2
goto end;
Here as we can't reference dh structure members directly, how can we initialize and set it in case of 1 and 2 ?
Thanks,
Priya

It is not possible to allocate opaque structures on the stack. The compiler will
complain.
