ndUDSRequestTransferExit

Purpose

Terminates a download/upload process.

Format

long ndUDSRequestTransferExit (
       TD1 *diagRef,
       unsigned char dataIn[],
       long len,
       unsigned char dataOut[],
       long *len2,
       LVBoolean *success);

Input

diagRef

Specifies the diagnostic session handle, obtained from ndOpenDiagnosticOnCANFD or ndOpenDiagnosticOnIPStack and passed to subsequent diagnostic functions. Normally, it is not necessary to manually manipulate the elements of this struct.

dataIn

Defines a data record to be written to the ECU as part of the termination process. The meaning is implementation dependent; this may be a checksum or a similar verification instrument.

len

Must be set to the buffer size for the dataIn parameter.

Output

dataOut

Returns a memory data block from the ECU as part of the termination process. The meaning is implementation dependent; this may be a checksum or a similar verification instrument.

len2

Must be set to the buffer size for the dataOut parameter. On return, it contains the actual data size returned in dataOut.

success

Indicates successful receipt of a positive response message for this diagnostic service.

Return Value

The return value indicates the function call status as a signed 32-bit integer. Zero means the function executed successfully. A negative value specifies an error, which means the function did not perform the expected behavior. A positive value specifies a warning, which means the function performed as expected, but a condition arose that may require attention.

Use the ndStatusToString function to obtain a descriptive string for the return value.

Description
