Returns the internal pathname in generic pathname format, converted to specific string type. Conversion, if any, is specified as follows:
- If
path::value_type
is char, conversion, if any, is system-dependent. This is the case on typical POSIX systems (such as Linux), where native encoding is UTF-8 andstring()
performs no conversion. - Otherwise, if
path::value_type
is wchar_t, conversion, if any, is unspecified. This is the case on Windows, where wchar_t is 16 bit and the native encoding is UTF-16. - Otherwise, if
path::value_type
is char16_t, native encoding is UTF-16 and the conversion method is unspecified. - Otherwise, if
path::value_type
is char32_t, native encoding is UTF-32 and the conversion method is unspecified. - Otherwise, if
path::value_type
is char8_t, native encoding is UTF-8 and the conversion method is unspecified.
The /
character is used as the directory separator.
1) All memory allocations are performed by

.3) The result encoding in the case of
u8string()
is always UTF-8.Parameters
