## Detailed Description

mangle, demangle (filename)

mangle or demangle filenames if they are greater than the max allowed characters for a given version of AFP.

## Macro Definition Documentation

## ◆ hextoint

#define hextoint | ( |  | c | ) |

Value:
( isdigit( c ) ? c - '0' : c + 10 - 'A' )
c
size_t c
Definition dircache.c:257

## ◆ isuxdigit

#define isuxdigit | ( |  | x | ) |

Value:
(isdigit(x) || (isupper(x) && isxdigit(x)))

Bug

  Early Mac OS X (10.0-10.4.?) had the limitation up to 255 Byte. Current implementation is: volcharset -> UTF16-MAC -> truncated 255 UTF8-MAC

  Recent Mac OS X (10.4.?-) don't have this limitation. Desirable implementation is: volcharset -> truncated 510 UTF16-MAC -> UTF8-MAC

Note
  with utf8 filename not always round trip
  filename mac filename too long or first chars if unmatchable chars.
  uname unix filename
  id file/folder ID or 0
  first
  static int first
  Definition nad_ls.c:56
  ID
  static uint16_t ID
