OpenSSL does not support platforms where the memory representation of
the NULL pointer contains non-zero bytes. IIRC there are even tests for
this.
Could someone from the OpenSSL team please explain the rationale for this
decision? What is the problem with using assignments with 0 or NULL to
initialize pointers?
I think you are confused.
There is no problem with what you posted. The issue is that if NULL != 0, OpenSSL won't necessarily work.
See test/sanitytest.c for what we check.
I'm not confused. The other answers in the thread already explained in
detail that NULL and 0 are equivalent for initializing pointers and that
memset() is not a portable way to initialize pointers, and I am aware of
that.
My question was meant to ask why the pointers are initialized with
memset() instead of initializing them by an assignment with NULL or 0.
Was this a deliberate decision for some reason, or did it just creep in
and no one cares now to fix it? Would the OpenSSL team accept pull
requests that fix this?
