.Sh DESCRIPTION
|
|
The
|
|
.Nm kiconv
|
|
library provides multi-byte character conversion tables for kernel side
|
|
iconv service.
|
|
.Pp
|
|
The
|
|
.Fn kiconv_add_xlat16_cspair
|
|
function
|
|
defines a conversion table using
|
|
.Xr iconv 3
|
|
between
|
|
.Fa fromcode
|
|
charset and
|
|
.Fa tocode
|
|
charset.
|
|
You can specify
|
|
.Fa flag
|
|
to determine if
|
|
.Xr tolower 3
|
|
/
|
|
.Xr toupper 3
|
|
conversion is included in the table.
|
|
The
|
|
.Fa flag
|
|
has following values.
|
|
.Pp
|
|
.Bl -tag -width ".Dv KICONV_FROM_LOWER" -compact
|
|
.It Dv KICONV_LOWER
|
|
.It Dv KICONV_FROM_LOWER
|
|
It generates a tolower table in addition to a character conversion table.
|
|
The difference between two is tolower
|
|
.Fa tocode
|
|
or tolower
|
|
.Fa fromcode .
|
|
.It Dv KICONV_UPPER
|
|
.It Dv KICONV_FROM_UPPER
|
|
It generates a toupper table in addition to a character conversion table.
|
|
The difference between two is toupper
|
|
.Fa tocode
|
|
or toupper
|
|
.Fa fromcode .
|
|
.El
|
|
.Pp
|
|
A tolower/toupper conversion is limited to single-byte characters.
|
|
.Pp
|
|
The
|
|
.Fn kiconv_add_xlat16_cspairs
|
|
function
|
|
defines two conversion tables which are from
|
|
.Fa localcode
|
|
to
|
|
.Fa foreigncode
|
|
and from
|
|
.Fa foreigncode
|
|
to
|
|
.Fa localcode .
|
|
These conversion tables also contain both tolower and toupper tables.
|
|
.Pp
|
|
The
|
|
.Fn kiconv_add_xlat16_table
|
|
function
|
|
defines a conversion table directly pointed by
|
|
.Fa data
|
|
whose length is
|
|
.Fa datalen ,
|
|
not using
|
|
.Xr iconv 3 .
