Returns the internal pathname in generic pathname format, converted to specific string type. Conversion, if any, is specified as follows:

• Ifpath::value_type ischar, 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, ifpath::value_type iswchar_t, conversion, if any, is unspecified. This is the case on Windows, wherewchar_t is 16 bit and the native encoding is UTF-16.
• Otherwise, ifpath::value_type ischar16_t, native encoding is UTF-16 and the conversion method is unspecified.
• Otherwise, ifpath::value_type ischar32_t, native encoding is UTF-32 and the conversion method is unspecified.
• Otherwise, ifpath::value_type ischar8_t, native encoding is UTF-8 and the conversion method is unspecified.

The/ character is used as the directory separator.
