Subject: Cast to right type for reserved_ subtraction (#6167)
X-Git-Tag: v2.0.0~209
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=77d57fd07560e1bfeccd34d1e4088cd36d3bf4be;p=platform%2Fupstream%2Fflatbuffers.git

Cast to right type for reserved_ subtraction (#6167)

reserved_ is a size_t so ensure that the output of cur_ - buf_ is cast to that to avoid compiler warnings.
