Re: [Boost-users] ptrdiff_t

I've check crtdefs.h on my system . It defined ptrdiff_t here but not under std namespace . Is the right place that ptrdiff_t got defined ? If not in which file should ptrdiff_t be defined . Maybe I should search the file where size_t got defined ? thanks in advance

Zitat von yushang:

I'm using boost with VC , when using array.hpp compiler complain the following error: 'ptrdiff_t' : is not a member of 'std' I searched ptrdiff_t definition in all files , found it defined in crtdefs.h which is not in namespace std. But array class has this

#include <cstddef>

array should include it though, if it doesn't please file a bug report: http://www.boost.org/support/bugs.html

ptrdiff_t *is* a member of 'std'. And boost/array.hpp *does* #include <cstddef>. At least at http://www.boost.org/doc/libs/1_43_0/boost/array.hpp

So yushang, do you really think it's a Boost bug?

Kind regards,
