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)
