Hello,

I'm trying to learn EPICS (complete newbie:) through an existing IOC application - instrumentation technologies libera IOC support application that uses asyn driver.
Since the existing driver is a bit complex, I'm trying to build my own version of the driver in order to understand mechanics of the EPICS. Also
existing libera IOC application is written in C++, while I'm trying to implement it in standard C instead.

I've successfully manages to get read/write operations on a PV to behave as expected. One thing that iocsh spews out during startup is this message:

PV: LIBERA01:ENV:ENV_KX_MONITOR scanAdd: I/O Intr not valid (no get_ioint_info)

the PVs are defined as follows (in db):
record(longin, "$(DEVICE)ENV_KX_MONITOR") {
        field(SCAN, "I/O Intr")
        field(INP, "@asyn($(PORT),700)")
        field(PINI, "YES")
}

record(longout, "$(DEVICE)ENV_KX_SP") {
        field(DTYP, "asynInt32")
        field(OUT, "@asyn($(PORT),700)")
}

Methods for read/write 32 int value:
static asynInt32 drvLiberaInt32 = {
   writeInt32,
   readInt32,
   NULL,
   NULL,
   NULL
};

As I said, reading from LIBERA01:ENV:ENV_KX_SP variable returns correct value and writing to the LIBERA01:ENV:ENV_KX_SP variable sets the value in the
desired device/port too. Using the LIBERA01:ENV:ENV_KX_MONITOR (via camonitor) does not reflect the same variable value as it should - same as LIBERA01:ENV:ENV_KX_SP.

How and where should one define 'get_ioint_info'?

I can't seem to get any reference to the get_ioint_info in existing C++ implementation of the driver..

Thank you,
Hinko
