Generic format observer functions return strings formatted according to the generic pathname format ([path.generic]). The forward slash ('/') character is used as the directory-separator character.
[ Example: On an operating system that uses backslash as its preferred-separator, path("foo\\bar").generic_string() returns "foo/bar". — end example ]
template <class EcharT, class traits = char_traits<EcharT>,
class Allocator = allocator<EcharT>>
basic_string<EcharT, traits, Allocator>
generic_string(const Allocator& a = Allocator()) const;
Returns: pathstring, reformatted according to the generic pathname format ([path.generic]).
Remarks: All memory allocation, including for the return value, shall be performed by a. Conversion, if any, is specified by [path.cvt].
std::string generic_string() const;
std::wstring generic_wstring() const;
std::string generic_u8string() const;
std::u16string generic_u16string() const;
std::u32string generic_u32string() const;
Returns: pathstring, reformatted according to the generic pathname format ([path.generic]).
Remarks: Conversion, if any, is specified by [path.cvt]. The encoding of the string returned by generic_u8string() is always UTF-8.
