Parameters:

pctxt

Pointer to a context structure.

Returns:: The length of the string or a negative status code if decoding failed.

EXTERNEXI int rtEXIDecTextToCharArray	(	OSCTXT *	pctxt,
		const OSUTF8CHAR *	target,
		size_t	start,
		size_t	length
	)

Similar to rtEXIDecText but the characters are copied into a fixed-size character array.

Parameters:

	pctxt	Pointer to a context structure.
	target	Destination array in which to copy the chars.
	start	Start index in target where the chars are copied.
	length	Maximum number of chars to copy.

Returns:: The actual number of chars copied into target or a negative error code if decoding failed.

EXTERNEXI int rtEXIDecUIntValue	(	OSCTXT *	pctxt,
		OSUINT32 *	pvalue
	)

This function decodes an unsigned integer value.

Parameters:

	pctxt	Pointer to context block structure.
	pvalue	Pointer to unsigned integer to receive decoded value.

Returns:

Completion status of operation:

0 = success,
negative return value is error.

EXTERNEXI int rtEXIDecUTF8Chars	(	OSCTXT *	pctxt,
		OSUTF8CHAR **	ppvalue,
		OSUINT32	nchars
	)

This function reads the given number of characters from the decode stream and creates a UTF-8 string.

Parameters:

	pctxt	Pointer to context block structure.
	ppvalue	Pointer to character string pointer to recive decoded string value. Memory for the string is allocated using rtxMemAlloc. It is freed using rtxMemFreePtr or when the context is freed.
	nchars	Number of characters to read from stream.

Returns:

Completion status of operation:

0 = success,
negative return value is error.

EXTERNEXI int rtEXIDecUTF8Str	(	OSCTXT *	pctxt,
		OSUTF8CHAR **	ppvalue
	)

This function decodes a UTF-8 string value.

Parameters:

	pctxt	Pointer to context block structure.
	ppvalue	Pointer to character string pointer to recive decoded string value. Memory for the string is allocated using rtxMemAlloc. It is freed using rtxMemFreePtr or when the context is freed.

Returns:

Completion status of operation:

0 = success,
negative return value is error.
