SpiEnumerateProtocols - Example Code

The following code illustrates how to return a list of stream protocol keys for the specified stream handler.

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

  ULONG         ulRC;                   /* Error return code */
  HID           hidTarget;              /* Target handler ID */
  ULONG         ulNumSPCBKeys = 20;     /* Number of entries */
  SPCBKEY       aspcbkey[20]; /* Array of SPCB keys*/

                            .
                            .
                            .
/*----------------------------------------------------------*/
/*  Get the stream handler ID (hidSource) for the file      */
/*  stream handler using SpiGetHandler.                     */
/*----------------------------------------------------------*/
                            .
                            .
                            .

/*----------------------------------------------------------*/
/*  Get a list of protocols for the digital audio stream
/*  handler.                                                */
/*----------------------------------------------------------*/
  if (ulRC = SpiEnumerateProtocols( hidTarget, &aspcbkey, &ulNumSPCBKeys))
     return(ulRC);                            /* error! */
