Can't find my USB-8451 in C

[Mikhak]

Hi

I'm simply trying to find the USB-8451 using this simple C code. But all I get back is "-301713", which corresponds to Invalid Parameter. Could someone please tell me what I'm doing wrong?

#include <windows.h>
#include <stdio.h>
#include <ni845x.h>

typedef unsigned int uint32;
typedef char         int8;
typedef long         int32;

int8 *pStatusString;
int32 status;
char *pFirstDevice;
uInt32 *pFindDeviceHandle;
uInt32 *pNumberFound;

int main(void)
{
	status = ni845xFindDevice(pFirstDevice,pFindDeviceHandle,pNumberFound);
	printf("Status: %d\n", status);

	getchar();
}

Hi Did you get the answer?

I got the same question now:mansad:

Hi I found out the question.

int32 status = 0;

char pFirstDevice[50];

uInt32 pFindDeviceHandle;

uInt32 pNumberFound;

status = ni845xFindDevice( pFirstDevice, &pFindDeviceHandle, &pNumberFound);
