Hi all,
I encountered the following errors while writing the processing function for the aSub record.
make -C O.linux-x86_64 -f ../Makefile TOP=../../.. \

My function（dose.c） content is as follows ：
#include <stdint.h>
#include <epicsExport.h>
#include <aSubRecord.h>
#include <registryFunction.h>
int dose(aSubRecord *psub) {
char *inData;
double *pout1, doseRate;
unsigned char readData[4] = {0};
double *p1, *p2;
inData = (char *)psub->a;
pout1 = (double *)psub->vala;
p1 = (double *)psub->valb;
p2 = (double *)psub->valc;
readData[0] = inData[4];
readData[1] = inData[3];
readData[2] = inData[6];
readData[3] = inData[5];
//Convert to floating point number
doseRate = *((float*)readData);
// result
*pout1 = doseRate;
return 0;
}
epicsRegisterFunction(dose);
