diagGetPrimitiveData, diagSetPrimitiveData

Valid for: CANoe DE

​
Function Syntax

  • long diagGetPrimitiveData (diagResponse obj, byte* buffer, DWORD buffersize)
  • long diagGetPrimitiveData (diagRequest obj, byte* buffer, DWORD buffersize)
  • long diagSetPrimitiveData (diagResponse obj, byte* buffer, DWORD buffersize)
  • long diagSetPrimitiveData (diagRequest obj, byte* buffer, DWORD buffersize)

​
Method Syntax

  • diagResponse::GetPrimitiveData (byte* buffer, DWORD buffersize)
  • diagRequest::GetPrimitiveData (byte* buffer, DWORD buffersize)
  • diagResponse::SetPrimitiveData (byte* buffer, DWORD buffersize)
  • diagRequest::SetPrimitiveData (byte* buffer, DWORD buffersize)

​
Description

Reads/sets the raw data of the complete service primitive (all data that is transmitted via the transport protocol). When setting the data the length of the primitive is not changed.

​
Parameters

  • objxt: Diagnostics object
  • buffer: Input/output buffer
  • buffersize: Buffer size

​
Return Values

Number of bytes copied into the buffer or error code

​
Example

// Print the length and first byte of a diagnostic request object
PrintDiagRequestBytes(diagRequest * req)
{
    BYTE primitiveRaw[4095];
    long size;
    size = DiagGetPrimitiveData(req, primitiveRaw, elcount(primitiveRaw));
    if(size > 0)
        write("Request = (%d)[%02x ...]", size, primitiveRaw[0]);
    else
        write("Request: error %d", size);
}
