145 zalloc must return Z_NULL if there is not enough memory for the object.

232 zalloc and zfree are set to Z_NULL, deflateInit updates them to use default

649 parameter is invalid (e.g. dictionary being Z_NULL) or the stream state is
663 Z_NULL, then only the dictionary length is returned, and nothing is copied.
664 Similarly, if dictLength is Z_NULL, then it is not set.
691 (such as zalloc being Z_NULL). msg is left unchanged in both source and
703 stream state was inconsistent (such as zalloc or state being Z_NULL).
785 or bits are Z_NULL, then those values are not set.
817 caller must assure that, if not Z_NULL, name and comment are terminated with
818 a zero byte, and that if extra is not Z_NULL, that extra_len bytes are

1165 strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
