Function Documentation

rtxLatin1ToUTF8()

EXTERNRT int rtxLatin1ToUTF8	(	const OSUTF8CHAR *	inbuf,
		int	inlen,
		OSUTF8CHAR *	outbuf,
		int	outbufsize
	)

This function converts an ISO 8859-1 encoded string into a UTF-8 string.

A buffer large enough to hold the converted UTF-8 characters must be provided. A buffer providing 4 bytes-per-character should be large enough to hold the largest possible UTF-8 conversion.

Parameters

inbuf	A pointer to an array of ISO 8859-1 characters.
inlen	Number of ISO 8859-1 characters to be converted.
outbuf	Buffer to hold converted string.
outbufsize	Size of output buffer.

Returns

Total number of bytes in converted string or a negative status code if error: -1 if lack of space

rtxStreamUTF8ToLatin1()

EXTERNRT int rtxStreamUTF8ToLatin1	(	OSCTXT *	pctxt,
		const OSUTF8CHAR *	inbuf,
		size_t	inlen
	)

This function converts a UTF-8 encoded byte stream into an ISO 8859-1 encoded string, and write it to stream.

Parameters

pctxt	Pointer to context block structure.
inbuf	A pointer to an array of UTF-8 string.
inlen	Number of bytes of the input string.

Returns

Total number of bytes in converted string or a negative status code if error: -1 if lack of space, or -2 if the transcoding fails

rtxUTF8ToLatin1()

EXTERNRT int rtxUTF8ToLatin1	(	const OSUTF8CHAR *	inbuf,
		int	inlen,
		OSUTF8CHAR *	outbuf,
		int	outbufsize
	)

This function converts a UTF-8 encoded byte stream into an ISO 8859-1 encoded string.

A buffer large enough to hold the converted characters must be provided.

Parameters

inbuf	A pointer to an array of UTF-8 string.
inlen	Number of bytes of the input string.
outbuf	Buffer to hold converted string.
outbufsize	Size of output buffer.

Returns

Total number of bytes in converted string or a negative status code if error: -1 if lack of space, or -2 if the transcoding fails
