I tried to create *.tdms file format with following codes. It did not create file and did not return any error codes. I could not find the problem. Would anyone let me know what the error was?
#define TDMS_FILE_TIT "Test 200 Hz TDMS data format"
#define TDMS_FILE_AUT "No Joen"
#define TDMS_ORION_200_HZ_CHANS 44
#define NUM_MAX_POINTS 44

tdmsError = TDMS_CreateFile(TDMS_FILE_PATH, TDMS_Streaming, TDMS_FILENAME,
TDMS_FILE_DESC, TDMS_FILE_TIT, TDMS_FILE_AUT, &hTdmsTestFileHandle);
tdmsError = TDMS_AddChannelGroup (hTdmsTestFileHandle, GROUP_NAME, GROUP_DESC, &hTdmsTestGroupHandle);

{
sprintf (szChanName, "point_%d", usChan);
sprintf (szChanDesc, "Data for channel %d", usChan);
tdmsError = TDMS_AddChannel (hTdmsTestGroupHandle, TDMS_Double, szChanName, szChanDesc, 0, &phChannels[usChan]);
