SpiSeekStream - Example Code

The following code illustrates how to seek a specified point in the stream source object or set the current stream time.

#include        "os2.h"
#include        "os2me.h"
#include        "stdio.h"

  ULONG         ulRC;                       /* Error return code   */
  HSTREAM       hStream;                    /* Stream handle       */
  LONG          lSeekPoint;                 /* Position to seek to */
                            .
                            .
                            .
/*----------------------------------------------------------------- ---*/
/*  Create a data stream, associate the data with the stream, and start*/
/*  streaming. (See SpiCreateStream, SpiAssociate, and SpiStartStream. */
/*---------------------------------------------------------------------*/
                            .
                            .
                            .
/*---------------------------------------------------------------------*/
/*  Seek to a position within the data stream.                         */
/*---------------------------------------------------------------------*/
  lSeekPoint = 900000;                    /* Seek to 5-minute position */

  if (ulRC = SpiSeekStream(hStream, SPI_SEEK_ABSOLUTE, lSeekPoint))
    return (ulRC);    /* Error! */
