GetValueLength()

virtual GDBResult SDK_CALLTYPE GetValueLength ( SDKUInt32 &  length ) const throw ( )

pure virtual

Returns the length of the attribute value in bytes.

Parameters

[out]

length

Address of a variable that receives the attribute value length.

CopyValue()

virtual GDBResult SDK_CALLTYPE CopyValue ( SDKUInt32  length, SDKUInt8 *  buffer  ) const throw ( )

pure virtual

Copies an attribute value to the buffer.

Parameters

length	[in] The buffer length.
buffer	[out] Pointer to the buffer that receives the attribute value.
