> [454|http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2577.html#454]
> proposes to change [filebuf.members] from:
> {quote}
> {noformat}
> basic_filebuf<charT,traits>* open(const char* s, ios_base::openmode mode);
> {noformat}
> ??Effects??: If {{is_open() != false}}, returns a null pointer.
> Otherwise, initializes the {{filebuf}} as required. It then opens a file, if
> possible, whose name is the NTBS ??s?? ("as if" by calling
> {{std::fopen(??s??, ??modstr??)}}).
> {quote}
> to:
> {quote}
> {noformat}
> basic_filebuf<charT,traits>* open(const char* s, ios_base::openmode mode);
> basic_filebuf<charT,traits>* open(const wchar_t* ws, ios_base::openmode
> mode);
> {noformat}
> ??Effects??: If {{is_open() != false}}, returns a null pointer.
> Otherwise, initializes the {{filebuf}} as required. It then opens a file, if
> possible, whose name is the NTBS ??s?? ("as if" by calling
> {{std::fopen(??s??, ??modstr??)}}). For the second signature, the NTBS ??s??
> is determined from the WCBS ??ws?? in an implementation-defined manner.
> (NOTE: For a system that "naturally" represents a filename as a WCBS, the
> NTBS ??s?? in the first signature may instead be mapped to a WCBS; if so, it
> follows the same mapping rules as the first argument to {{open}}.)
