Re: fstream on linuxx8664gcc platform

Hello, Kerry,

I need more information about basic_streambuf::tellg() and pos_type. Will you try following commands on both environment and tell me what you see?

Thank you
Masa Goto

$ root
root> type ostream::pos_type

     ...
root> type mbstate_t

     ...
root> class mbstate_t

     ...
root> class fpos<mbstate_t>

     ...
