kiconv_add_xlat16_table
KICONV(3) BSD Library Functions Manual KICONV(3)
NAME
kiconv_add_xlat16_cspair, kiconv_add_xlat16_cspairs, kiconv_add_xlat16_table -- kernel side iconv library
LIBRARY
Kernel side iconv library (libkiconv, -lkiconv)
SYNOPSIS
#include <sys/iconv.h>
int
kiconv_add_xlat16_cspair(const char *tocode, const char *fromcode, int flag);
int
kiconv_add_xlat16_cspairs(const char *foreigncode, const char *localcode);
int
kiconv_add_xlat16_table(const char *tocode, const char *fromcode, const void *data, int datalen);
DESCRIPTION
The kiconv library provides multi-byte character conversion tables for kernel side iconv service.
The kiconv_add_xlat16_cspair() function defines a conversion table using iconv(3) between fromcode charset and tocode charset. You can spec-
ify flag to determine if tolower(3) / toupper(3) conversion is included in the table. The flag has following values.
KICONV_LOWER
KICONV_FROM_LOWER It generates a tolower table in addition to a character conversion table. The difference between two is tolower tocode or
tolower fromcode.
KICONV_UPPER
KICONV_FROM_UPPER It generates a toupper table in addition to a character conversion table. The difference between two is toupper tocode or
toupper fromcode.
A tolower/toupper conversion is limited to single-byte characters.
The kiconv_add_xlat16_cspairs() function defines two conversion tables which are from localcode to foreigncode and from foreigncode to
localcode. These conversion tables also contain both tolower and toupper tables.
The kiconv_add_xlat16_table() function defines a conversion table directly pointed by data whose length is datalen, not using iconv(3).
