WriteClassStm function

The WriteClassStm function stores the specified CLSID in the stream.

Syntax


WINOLEAPI WriteClassStm(
  _In_ IStream  *pStm,
  _In_ REFCLSID rclsid
);

Parameters

pStm [in]

IStream pointer to the stream into which the CLSID is to be written.

rclsid [in]

Specifies the CLSID to write to the stream.

Return value

S_OK

Indicates that the CLSID was successfully written.

STG_E_MEDIUMFULL

The CLSID could not be written because there is no space left on device.

Remarks

The WriteClassStm function writes a CLSID to the specified stream object so it can be read by the ReadClassStm function. Most applications do not call WriteClassStm directly. OLE calls it before making a call to an object's IPersistStream::Save method.
