_Wide_alloc = allocator<_Elem>, typename _Byte_alloc = allocator<char>> std::wstring_convert*< _Codecvt, _Elem, _Wide_alloc, _Byte_alloc >::*wstring_convert ()= [inline]= Default constructor.

Definition at line 241 of file locale_conv.h.

template<typename _Codecvt , typename _Elem = wchar_t, typename

_Wide_alloc = allocator<_Elem>, typename _Byte_alloc = allocator<char>> std::wstring_convert*< _Codecvt, _Elem, _Wide_alloc, _Byte_alloc >::*wstring_convert (_Codecvt * __pcvt)= [inline]=, = [explicit]= Constructor.

Parameters

__pcvt The facet to use for conversions.

Takes ownership of __pcvt and will delete it in the destructor.

Definition at line 250 of file locale_conv.h.

template<typename _Codecvt , typename _Elem = wchar_t, typename

_Wide_alloc = allocator<_Elem>, typename _Byte_alloc = allocator<char>> std::wstring_convert*< _Codecvt, _Elem, _Wide_alloc, _Byte_alloc >::*wstring_convert (_Codecvt * __pcvt, state_type __state)= [inline]= Construct with an initial converstion state.

Parameters

__pcvt The facet to use for conversions.
__state Initial conversion state.

Takes ownership of __pcvt and will delete it in the destructor. The object’s conversion state will persist between conversions.

Parameters

/__byte_err/* A string to return on failed conversions.
__wide_err
A wide string to return on failed conversions. *
