## 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.

## ◆ 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.

## ◆ atalk_iconv_close()

int atalk_iconv_close | ( | atalk_iconv_t | cd | ) |

simple iconv_close() wrapper

## ◆ atalk_iconv_open()

atalk_iconv_t atalk_iconv_open | ( | const char * | tocode,
|  | const char * | fromcode )

simple iconv_open() wrapper

## ◆ atalk_register_charset()

int atalk_register_charset | ( | struct charset_functions * | funcs | ) |

## ◆ find_charset_functions()

struct charset_functions * find_charset_functions | ( | const char * | name | ) |

## ◆ iconv_copy()

size_t iconv_copy | ( | void * | cd,
|  | char ** | inbuf,
|  | size_t * | inbytesleft,
|  | char ** | outbuf,
|  | size_t * | outbytesleft )
| static

## ◆ lazy_initialize_iconv()

void lazy_initialize_iconv | ( | void |  | ) |
| static

## ◆ sys_iconv()

size_t sys_iconv | ( | void * | cd,
|  | char ** | inbuf,
|  | size_t * | inbytesleft,
|  | char ** | outbuf,
|  | size_t * | outbytesleft )
| static
