I'll retract my previous post (..)

Setting up your example gets me a different result though, the one you

expect - The only part I miss is field(INAM, "mySubInit"), maybe

something there? This is the outpout I got

DBR_DOUBLE:         0

Record HAD:RPC:S1:M0:C9:stToTL called myStoreFcn(0x8415b58), thr 200,

precord->d 200.000000

doubles need %lf to printf.
Could that be your problem ??

#include <stdio.h>
int main (int argc, char *argv[]) {
    double f=200.;
    float *pf = (float*)&f;
    printf ("%f\n",*pf);
    printf ("%lf\n",*(double*)pf);
    return 0;
}
