Hi All,
I am trying to build my VC++ 2010 application in VC++ 2015,
After building getting a error message "_buf_size is not a member of _io_size"
but before the same Application is running on VC++ 2010...
what is meaning of that error and how do I solve in VC++ 2015...
Regards,
Asha.

I'm guessing that your code relied on some undocumented internal implementation that's now changed.
You'll need to show a simple repro before anyone can do other than guess though.
As @David Lowndes indicated there were changes to the CRT between VC++ 2010 and VC++2015. In fact, the changes were a complete refactoring and broke any old code that relied on undocumented features of the VC++ 2010 CRT.
