Detailed Description

wrapper/stub for iconv character set conversion.

iconv is an interface for converting between character encodings. This file, forked from samba, provides a wrapper around it, and also a simple reimplementation that is used if the system does not implement iconv.

Note

the only function provided by iconv is conversion between characters. It doesn't directly support operations like uppercasing or comparison. We have to convert to UCS-2 and compare there.

Macro Definition Documentation

CHARSET_WIDECHAR

#define CHARSET_WIDECHAR   32

DLIST_ADD

#define DLIST_ADD	(		list,
			p )

Value:

{ \
        if (!(list)) { \
                (list) = (p); \
                (p)->next = (p)->prev = NULL; \
        } else { \
                (list)->prev = (p); \
                (p)->next = (list); \
                (p)->prev = NULL; \
                (list) = (p); \
        }\
}

UCS2ICONV

#define UCS2ICONV   "UCS-2LE"

Function Documentation

ascii_pull()

size_t ascii_pull ( void * cd, char ** inbuf, size_t * inbytesleft, char ** outbuf, size_t * outbytesleft )

static

ascii_push()

size_t ascii_push ( void * cd, char ** inbuf, size_t * inbytesleft, char ** outbuf, size_t * outbytesleft )

static

atalk_iconv()

size_t atalk_iconv	(	atalk_iconv_t	cd,
		const char **	inbuf,
		size_t *	inbytesleft,
		char **	outbuf,
		size_t *	outbytesleft )

This is a simple portable iconv() implementaion.

It only knows about a very small number of character sets - just enough that netatalk works on systems that don't have iconv.
