This method reads a specified number of bytes from the stream object into memory, starting at the current seek pointer.

HRESULT Read( 
void *pv, 
ULONG cb, 
ULONG *pcbRead 
);

Parameters

• pv
  [out] Pointer to the buffer into which the stream data is read. If an error occurs, this value is NULL.
• cb
  [in] Specifies the number of bytes of data to attempt to read from the stream object.
