Hi,
I'm having some very basic problems with the C API. Using the following code always returns -1 in the last call. Using the Python API to do the same thing works fine. Any ideas?
#include <stdio.h>
#include "okFrontPanelDLL.h"
void main(void) {
okFrontPanel_HANDLE ok_handle;
int rc = 0;
if (FALSE == okFrontPanelDLL_LoadLib(NULL)) {
printf("FrontPanel DLL could not be loaded\n");
rc = -1;
}
if (!rc) {
char serial[MAX_SERIALNUMBER_LENGTH+1];
ok_handle = okFrontPanel_Construct();
if (ok_NoError != okFrontPanel_IsOpen(ok_handle)) {
printf("Is already open. Closing first\n");
okFrontPanel_Close(ok_handle);
}
int ec = okFrontPanel_OpenBySerial(ok_handle, serial);
if (ec != ok_NoError) {
printf("Error %d: Device could not be opened. Is one connected?\n",ec);
rc = -2;
}
}
}
