VJFORCEREG structure

The VJFORCEREG structure registers the callbacks to the ring 0 (kernel-mode) force-feedback driver.

Syntax

typedef struct {
  DWORD              dwSize;
  SETGAINRTN         fpSetFFGain;
  SENDFFCOMMANDRTN   fpSendFFCommand;
  GETFFSTATERTN      fpGetFFState;
  DOWNLOADEFFECTRTN  fpDownloadEff;
  DESTROYEFFECTRTN   fpDestroyEff;
  STARTEFFECTRTN     fpStartEff;
  STOPEFFECTRTN      fpStopEff;
  GETEFFECTSTATUSRTN fpGetStatusEff;
} VJFORCEREG, *VJLPFORCEREG;
