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

Parameters

a - allocator to construct the string with
Type requirements
-CharT must be one of the encoded character types (char, wchar_t, char16_t and char32_t)

Return value

The internal pathname in generic pathname format, converted to specified string type.

Exceptions

(none).
