character string c++ Is wifstream(wchar_t*) missing in STL?
Hello all, I am trying to write code using only wide character set and what a suprise: I could not find the constructor for wifstream(wchar_t* file_name) in STL. Is this right? I need to open a file which name is represented in wide characters. Is there any other way to do it using standard C++ library without resorting to converting to char*. Thanx. Happy programming.

The wide-oriented streams in both C and C++ support reading and writing of data that is represented as wide characterss. Neither language supports naming files with wide characterss.

Hello all, I am trying to write code using only wide character set and what a suprise: I could not find the constructor for wifstream(wchar_t* file_name) in STL. What compiler/STL are you using. EGCS1.1 & GNU do not have proper iostreams.(i.e. they do not have the templated basic_istream<Ch,Traits etc. Is this right? I need to open a file which name is represented in wide characters. Is there any other way to do it using standard C++ library without resorting to converting to char*. Thanx. Happy programming.

because operating systems and their file systems are not under the control of the language standard, and not all platforms support these features. If such functions were added to the language it would either become impossible to have a conforming implementation on platforms without the features, or strictly conforming code using these features would not be portable to all conforming implementations. It just isn't so. Constructing a fstream with a name string of (narrow-characters), say, +++++ , is fully conforming
