SMH_REGISTER - Example Code

The following code illustrates how to register a stream handler with the Sync/Stream Manager.

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

    #define         RegName      "C:\PATH\TESTSH" /* Handler name and path  */

  ULONG         ulRC;                         /* Error return code          */
  HID           hidSource,                    /* Source handler ID          */
                hidTarget;                    /* Target handler ID          */
  PARM_REG      parm_reg;                     /* Register parameter block   */
  PSMHFN        SMHEntryPoint;                /* Pointer to SMH entry point */

/*--------------------------------------------------------------------------*/
/*  Register a stream handler as both source and target.                    */
/*--------------------------------------------------------------------------*/

  parm_reg.ulFunction = SMH_REGISTER;         /* Set function.        */
  parm_reg.pszSHName = (PSZ) RegName;         /* Set handler name.    */
  parm_reg.phidSrc = &hidMSrc;                /* Returns source hid.          */
  parm_reg.phidTgt = &hidMTgt;                /* Returns target hid.          */
  parm_reg.ulFlags = REGISTER_TGT_HNDLR | REGISTER_SRC_HNDLR;
                                              /* Register as a source
                                                 and target stream handler. */
  parm_reg.pshcfnEntry = (PSHCFN) main;       /* Entry point address.    */

  if (ulRC = SMHEntryPoint (&parm_reg))
     return(ulRC);                               /* Error! */
