@Generated("io.github.jwharm.JavaGI")
public class IConv
extends ProxyInstance

The GIConv struct wraps an iconv() conversion descriptor. It contains private data and should only be accessed using the following functions.

Constructor Summary

Constructors

Constructor	Description
IConv(MemorySegment address)	Create a IConv proxy instance for the provided memory address.

Method Summary

Modifier and Type	Method	Description
int	close()	Same as the standard UNIX routine iconv_close(), but may be implemented via libiconv on UNIX flavors that lack a native implementation.
long	iconv(String[] inbuf, Out<Long> inbytesLeft, String[] outbuf, Out<Long> outbytesLeft)	Same as the standard UNIX routine iconv(), but may be implemented via libiconv on UNIX flavors that lack a native implementation.
static IConv	open(String toCodeset, String fromCodeset)	Same as the standard UNIX routine iconv_open(), but may be implemented via libiconv on UNIX flavors that lack a native implementation.

Constructor Details

IConv

public IConv(MemorySegment address)

Create a IConv proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

open

public static IConv open(String toCodeset,
 String fromCodeset)

Same as the standard UNIX routine iconv_open(), but may be implemented via libiconv on UNIX flavors that lack a native implementation.

GLib provides g_convert() and g_locale_to_utf8() which are likely more convenient than the raw iconv wrappers.

Parameters:

toCodeset - destination codeset

fromCodeset - source codeset

Returns:

a "conversion descriptor", or (GIConv)-1 if opening the converter failed.

iconv

public long iconv(String[] inbuf,
 Out<Long> inbytesLeft,
 String[] outbuf,
 Out<Long> outbytesLeft)

Same as the standard UNIX routine iconv(), but may be implemented via libiconv on UNIX flavors that lack a native implementation.

GLib provides g_convert() and g_locale_to_utf8() which are likely more convenient than the raw iconv wrappers.

Note that the behaviour of iconv() for characters which are valid in the input character set, but which have no representation in the output character set, is implementation defined. This function may return success (with a positive number of non-reversible conversions as replacement characters were used), or it may return -1 and set an error such as EILSEQ, in such a situation.

Parameters:

inbuf - bytes to convert

inbytesLeft - inout parameter, bytes remaining to convert in inbuf

outbuf - converted output bytes

outbytesLeft - inout parameter, bytes available to fill in outbuf

Returns:

count of non-reversible conversions, or -1 on error

close

public int close()

Same as the standard UNIX routine iconv_close(), but may be implemented via libiconv on UNIX flavors that lack a native implementation. Should be called to clean up the conversion descriptor from g_iconv_open() when you are done converting things.

GLib provides g_convert() and g_locale_to_utf8() which are likely more convenient than the raw iconv wrappers.

Returns:

-1 on error, 0 on success
