Function Documentation

int rtXmlDecBase64Binary	(	OSRTMEMBUF *	pMemBuf,
		const OSUTF8CHAR *	inpdata,
		OSSIZE	length
	)

This function decodes the contents of a Base64-encoded binary data type into a memory buffer.

Input is expected to be a string of UTF-8 characters returned by an XML parser. The decoded data will be put into the memory buffer starting from the current position and bit offset. After all data is decoded the octet string may be fetched out.

This function is normally used in the 'characters' SAX handler.

Parameters:

	pMemBuf	Memory buffer to which decoded binary data is to be appended.
	inpdata	Pointer to a source string to be decoded.
	length	Length of the source string (in characters).

Returns:

Completion status of operation:

• 0 = success,
• negative return value is error.

int rtXmlDecBase64Str	(	OSCTXT *	pctxt,
		OSOCTET *	pvalue,
		OSUINT32 *	pnocts,
		OSINT32	bufsize
	)

This function decodes a contents of a Base64-encode binary string into a static memory structure.

The octet string must be Base64 encoded. This function call is used to decode a sized base64Binary string production.

Parameters:

	pctxt	A pointer to a context structure. This provides a storage area for the function to store all working variables that must be maintained between function calls.
	pvalue	A pointer to a variable to receive the decoded bit string. This is assumed to be a static array large enough to hold the number of octets specified in the bufsize input parameter.
	pnocts	A pointer to an integer value to receive the decoded number of octets.
	bufsize	The size (in octets) of the sized octet string. An error will occur if the number of octets in the decoded string is larger than this value.

Returns:

Completion status of operation:

• 0 = success,
• negative return value is error.

int rtXmlDecBase64StrValue	(	OSCTXT *	pctxt,
		OSOCTET *	pvalue,
		OSUINT32 *	pnocts,
		OSSIZE	bufSize,
		OSSIZE	srcDataLen
	)

This function decodes a contents of a Base64-encode binary string into the specified octet array.

The octet string must be Base64 encoded. This function call is used internally to decode both sized and non-sized base64binary string production.

Parameters:

	pctxt	A pointer to a context structure. This provides a storage area for the function to store all working variables that must be maintained between function calls.
	pvalue	A pointer to a variable to receive the decoded bit string. This is assumed to be a static array large enough to hold the number of octets specified in the bufsize input parameter.
	pnocts	A pointer to an integer value to receive the decoded number of octets.
	bufSize	A maximum size (in octets) of pvalue buffer. An error will occur if the number of octets in the decoded string is larger than this value.
	srcDataLen	An actual source data length (in octets) without whitespaces.

Returns:

Completion status of operation:

• 0 = success,
• negative return value is error.
