parserutils_error parserutils_charset_codec_create	(	const char *	charset,
		parserutils_charset_codec **	codec
	)

Create a charset codec.

Parameters:

charset	Target charset
codec	Pointer to location to receive codec instance

Returns:: PARSERUTILS_OK on success, PARSERUTILS_BADPARM on bad parameters, PARSERUTILS_NOMEM on memory exhaustion, PARSERUTILS_BADENCODING on unsupported charset

parserutils_error parserutils_charset_codec_decode	(	parserutils_charset_codec *	codec,
		const uint8_t **	source,
		size_t *	sourcelen,
		uint8_t **	dest,
		size_t *	destlen
	)

Decode a chunk of data in a codec's charset into UCS-4.

Parameters:

codec	The codec to use
source	Pointer to pointer to source data
sourcelen	Pointer to length (in bytes) of source data
dest	Pointer to pointer to output buffer
destlen	Pointer to length (in bytes) of output buffer

Returns:: PARSERUTILS_OK on success, appropriate error otherwise.

source, sourcelen, dest and destlen will be updated appropriately on exit

Call this with a source length of 0 to flush any buffers.
