write and read functions in asyn

[高振华 via Tech-talk <tech-talk@aps.anl.gov>]

Hi all,

I saw the prototype declarations for the write and read functions in this. h file(asyn/asyn/interfaces/asynInt32.h),

But I couldn't find the bodies of the write and read functions,

Does anyone know where it is?

typedef struct asynInt32 {

    asynStatus (*write)(void *drvPvt, asynUser *pasynUser, epicsInt32 value);

    asynStatus (*read)(void *drvPvt, asynUser *pasynUser, epicsInt32 *value);

    asynStatus (*getBounds)(void *drvPvt, asynUser *pasynUser,

                           epicsInt32 *low, epicsInt32 *high);

    asynStatus (*registerInterruptUser)(void *drvPvt,asynUser *pasynUser,

                           interruptCallbackInt32 callback, void *userPvt,

                           void **registrarPvt);

    asynStatus (*cancelInterruptUser)(void *drvPvt, asynUser *pasynUser,

                           void *registrarPvt);

} asynInt32;

Thanks,

Gao Zhenhua
