CfXitData Structure

The CfXitData structure is contained in the CfXitData.h file, which is by default located in the $CFROOT/samples directory.

See the following example of the CfXitData.h file: 

typedef struct __CfXitData {	
	int StatusDiagCode;
	BYTE StatusSeverity;
	BYTE Compression;
	char RecordFormat[2];
	short int BlockSize; 
	BYTE PermittedActions;
	char StatusMsg[255]; 
	char LocalUserId[255];
	DWORD Key;
	DWORD AllocationPrimary;
	DWORD AllocationSecondary;
	DWORD RecordLength;
	DWORD EncryptionType;
	char VolSer[7];
	int IsVolSer;
	char UNIT[9];
	int IsUnit;
	char AllocationType[2];
	char NewFileAvail[2];
	char LocalPassword[255];
	char IpAddress[255];
	char RemoteUserId[255];
	char RemotePassword[255];
	char RemoteDomain[255];
	char LocalFileName[255];
	char RemoteFileName[255];
	char TraceFileName[255];
	char WriteMode[2];
	char TransferFunction[2];
	char TransactionNumber[11];
	char TransferWork[2];
	char CheckPointRestart[2];
	char CR_LF[2];
	int DataType;
	int Port;
	DWORD ByteCount;
	BOOL FirstTime;
	int GoingToRetry;
	int TryCount;
	int TriedCount;
}CfXitData;
The following table lists the parameters that define the CfXitData structure:
Field Names Data Type Field Values
StatusDiagCode int Indicates the return code on reply:
  • x00: Success
  • x01: Failure
  • x09: Abort
StatusSeverity BYTE Indicates the severity of the transfer status:
  • x00: Success
  • x01: Informational
  • x02: Warning
  • x03: Error
  • x10: No Checkpoint
  • x20: No Restart
  • x80: Retry network error
  • x81: Retry file error
Compression BYTE Indicates the type of compressions:
  • x00: No compression
  • x11: LZ compression
  • x12: RLE compression
RecordFormat char[2] Indicates the remote file record format:
  • F: Fixed blocked
  • V: Variable blocked
  • U: Undefined
  • X: Fixed
  • Y: Variable
BlockSize Short int Indicates the z/OS dataset block size.
PermittedActions BYTE Indicates the type of permitted actions:
  • x00: None
  • x02: EOF
  • x04: CRLFEOF
  • x08: System
  • x10: Hidden
  • x20: Archive
  • x40: Read Only
  • x80: NTFS Compressed
StatusMsg char[255] Indicates the text message with transfer status.
LocalUserId char[255] Indicates the local user ID that initiates the transfer.
AllocationPrimary DWORD Indicates the initial number of units for physical storage to allocate when creating datasets.
AllocationSecondary DWORD Indicates the next number of units for physical storage to allocate as soon as the initial allocation in the datasets is used up.
RecordLength DWORD Indicates the maximum logical record length, that is, the string length used to encode the data records of the file.

The maximum logical record length in a z/OS system is 32,760.

For best results, you might omit this parameter if you want to send or receive a file into a file that already exists, because the file can be determined with an appropriate length .

Note: This parameter is ignored when you perform a send transfer to TIBCO MFT Platform Server for Windows, because it is a z/OS-specific parameter.
EncryptionType DWORD Indicates the type of encryption:
  • x80: Data is not encrypted (check x00 too)
  • x40: DES Encryption
  • x20: 3DE Encryption
  • x10: Blowfish Encryption
  • x08: Blowfish Long
  • x04: Rijndael
  • x00: No encryption (check x80 too)
VolSer char[7] Indicates the remote file volume name.
IsVolSer int N/A
UNIT char[9] Indicates the remote file unit name.
IsUnit int N/A
AllocationType char[2] Indicates the type of allocation:
  • T: Tracks
  • C: Cylinders
  • K: Kilobytes
  • M: Megabytes
NewFileAvail char[2] Indicates whether the new file is available:
  • I: Immediate
  • D: Deferred (Tape)
LocalPassword char[255] Indicates the password for local system (occasionally NULL).
