SpiEnableEvent - Example Code

The following code illustrates how to enable event notification for a particular event.

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

  ULONG         ulRC;                    /* Error return code           */

  HSTREAM       hStream;                 /* Stream handle               */
  TIME_EVCB     TIMEEVCB = [0,0,0,0,0,0,0,0,0]; /* Cue point event      */
  HEVENT        hevent;                       /* Event handle           */
                            .
                            .
                            .

/*  Set an event.                                                      */

     return (ulRC);    /* error! */
