kiconv_open - code conversion descriptor allocation function

#include <sys/sunddi.h>



kiconv_t kiconv_open(const char *tocode, const char *fromcode);

illumos DDI specific (illumos DDI). tocode fromcode The kiconv_open() function returns a code conversion descriptor that describes a conversion from the codeset specified by fromcode to the codeset specified by tocode. For state-dependent encodings, the conversion descriptor is in a codeset-dependent initial state (ready for immediate use with the kiconv() function).

Supported code conversions are between UTF-8 and the following:

A conversion descriptor remains valid until it is closed by using kiconv_close().

Upon successful completion, kiconv_open() returns a code conversion descriptor for use on subsequent calls to kiconv(). Otherwise, if the conversion specified by fromcode and tocode is not supported or for any other reasons the code conversion descriptor cannot be allocated, kiconv_open() returns (kiconv_t)-1 to indicate the error. kiconv_open() can be called from user context only. Example 1 Opening a Code Conversion

The following example shows how to open a code conversion from ISO 8859-15 to UTF-8

#include <sys/sunddi.h>

kiconv_t cd;

cd = kiconv_open("UTF-8", "ISO-8859-15");
if (cd == (kiconv_t)-1) {
 /* Cannot open up the code conversion. */
 return (-1);
}

The Unicode Standard

http://www.unicode.org/standard/standard.html

The code conversions are available between UTF-8 and the above noted codesets. For example, to convert from EUC-JP to Shift_JIS, first convert EUC-JP to UTF-8 and then convert UTF-8 to Shift_JIS.

The code conversions supported are based on simple one-to-one mappings. There is no special treatment or processing done during code conversions such as case conversion, Unicode Normalization, or mapping between combining or conjoining sequences of UTF-8 and pre-composed characters in non-UTF-8 codesets.

All supported non-UTF-8 codesets use pre-composed characters only. However, UTF-8 allows combining or conjoining characters too. For this reason, using a form of Unicode Normalizations on UTF-8 text with u8_textprep_str() before or after doing code conversions might be necessary.
