s size_t additions

i have formula warning giveaway vs.net gcc, i have formula 64-bit ready.

today i wrote small way deals memory buffers provides opening information around file-style interface (e.g. review bytes, bytes, find around etc.).

as data-type tide review position distance i used size_t given seems many healthy choice. i around warnings ought work 64-bit well.

just case: structure looks this:

typedef struct
{
  unsigned bake * m_data;
  size_t          m_currentreadposition;
  size_t          m_datasize;
} mymemoryfile;

the signedness size_t seems tangible practice. google code-search current that.

now i'm dilemma: i wish check additions size_t s since i have understanding user reputed information third jubilee libraries code. however, yield check i have know sign-ness. creates vast inadequacy implementation.

so - heck should i such formula height compiler individualist way?

can i check signedness size_t during run compile-time? solve problem. maybe size_t wasn't best thought initial place.

any ideas?

edit: i'm looking fortitude c-language!
