History

Jonathan Wakely b02923592a Add support for opening file streams from wide character strings C++17 added new overloads to <fstream> class templates to support opening files from wide character strings "on systems where filesystem::path::value_type is not char". This patch adds those overloads conditional on _wfopen being available, and enables them for pre-C++17 modes as well. Add support for opening file streams from wide character strings. * config/io/basic_file_stdio.cc [_GLIBCXX_HAVE__WFOPEN] (__basic_file<char>::open(const wchar_t, ios_base::openmode)): Define new overload. config/io/basic_file_stdio.h [_GLIBCXX_HAVE__WFOPEN] (__basic_file<char>::open(const wchar_t, ios_base::openmode)): Declare new overload. configure.ac: Check for _wfopen. * crossconfig.m4: Likewise. * configure: Regenerate. * config.h.in: Regenerate. * include/bits/fstream.tcc [_GLIBCXX_HAVE__WFOPEN] (basic_filebuf<C,T>::open(const wchar_t, ios_base::openmode)): Define new overload. include/std/fstream [_GLIBCXX_HAVE__WFOPEN] (basic_filebuf<C,T>::open(const wchar_t, ios_base::openmode)): Declare new overload. [_GLIBCXX_HAVE__WFOPEN] (basic_ifstream<C,T>::basic_ifstream(const wchar_t, openmode)) (basic_ifstream<C,T>::basic_open(const wchar_t, openmode)) (basic_ofstream<C,T>::basic_ifstream(const wchar_t, openmode)) (basic_ofstream<C,T>::basic_open(const wchar_t, openmode)) (basic_fstream<C,T>::basic_ifstream(const wchar_t, openmode)) (basic_fstream<C,T>::basic_open(const wchar_t, openmode)): Define new overloads. testsuite/27_io/basic_filebuf/open/wchar_t/1.cc: New. * testsuite/27_io/basic_ifstream/cons/wchar_t/1.cc: New. * testsuite/27_io/basic_ifstream/open/wchar_t/1.cc: New. * testsuite/27_io/basic_ofstream/cons/wchar_t/1.cc: New. * testsuite/27_io/basic_ofstream/open/wchar_t/1.cc: New. * testsuite/27_io/basic_fstream/cons/wchar_t/1.cc: New. * testsuite/27_io/basic_fstream/open/wchar_t/1.cc: New.
