ndRequestRoutineResultsByLocalIdentifier
Purpose
Executes the RequestRoutineResultsByLocalIdentifier service. Returns results from an ECU
routine.
Format
long ndRequestRoutineResultsByLocalIdentifier(
TD1 *diagRef,
unsigned char localID,
unsigned char dataOut[],
long *len,
LVBoolean *success);
Input
diagRef
Specifies the diagnostic session handle, obtained from ndOpenDiagnostic and passed
to subsequent diagnostic functions. Normally, it is not necessary to manually manipulate
the elements of this struct.
localID
Defines the local identifier of the routine from which this function retrieves results. The
values are application specific.
Output
dataOut
Returns application-specific output parameters from the routine.
len
On input, len must contain the dataOut array length. On return, it contains the number
of valid data bytes in the
dataOut array.
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.
