WsSetInputToBuffer function (webservices.h)

Sets Reader input to a specified XML buffer. Reader properties specified to WsSetInputToBuffer override properties set by WsCreateReader.

The reader does not modify WS_XML_BUFFER input data.

Note  It is permissible for more than one reader to read from the same WS_XML_BUFFER.

Return value

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.


When an XML Reader has an XML Buffer as an input source, the Reader can be used in a random access fashion, and the functions WsGetReaderPosition, WsSetReaderPosition, and WsMoveReader are available for use.
