I would like to write nidaqmx provided by ni in language c. However, there is a problem with quoting the header file. I wonder if this is the right way to write in the contents after #include. And when it is executed in this way, there are no other errors, but there are several errors called "link2019. I want to know if the header file citation failed or if the header file and source file configuration are wrong. I may have lacked foundation because I just started learning C language.
#include <stdio.h>
#include "C:\Program Files (x86)\National Instruments\NI-DAQ\DAQmx ANSI C Dev\include\NIDAQmx.h"
#define DAQmxErrChk(functionCall) if( DAQmxFailed(error=(functionCall)) ) goto Error; else
int main(void)
{
int32 error = 0;
TaskHandle taskHandle = 0;
int32 read;
float64 data[1000];
char errBuff[2048] = { '\0' };
/*********************************************/

DAQmxErrChk(DAQmxCreateTask("", &taskHandle));
DAQmxErrChk(DAQmxCreateAIVoltageChan(taskHandle, "Dev1/ai0", "", DAQmx_Val_Cfg_Default, -10.0, 10.0, DAQmx_Val_Volts, NULL));
DAQmxErrChk(DAQmxCfgSampClkTiming(taskHandle, "", 10000.0, DAQmx_Val_Rising, DAQmx_Val_FiniteSamps, 1000));
