The following code illustrates how to remove a stream from the system.
#include        "os2.h"
#include        "os2me.h"
  ULONG         ulRC;              /* Error return code */
  HSTREAM       hStream;           /* Stream handle     */
                            .
                            .
                            .
/*------------------------------------------------------*/
/*  Create a data stream (hStream) and process the data.*/
/*------------------------------------------------------*/
                            .
                            .
                            .
/*------------------------------------------------*/
/*  Finished with stream - Now destroy the stream.*/
/*------------------------------------------------*/
  if (ulRC = SpiDestroyStream(hStream))
    return (ulRC);    /* error! */
