Hi Titan experts,

Unfortunately my TTCN ATS defines one external function returning a template. Below a simplified example:

  external function fx_Test(octetstring p_Data) return template (omit) octetstring;


The idea is that in particular data conditions the external function returns omit
My test implementation (not yet correct) in C is:

 OCTETSTRING_template fx__Test(const OCTETSTRING &p_Data) {
  
    const uint8_t *data_in = p_Data;
    uint8_t data_out[2];
    OCTETSTRING_template v_ReturnVal;

    data_out[0] = data_in[0];
    data_out[1] = data_in[1];
    if (data_in[0] == 0x0) {
      // FFS - Set v_ReturnVal to omit
      return v_ReturnVal;
    }
   v_ReturnVal = OCTETSTRING(2, data_out);
    return v_ReturnVal;
  }
 


My question: How can I set in my C implementation v_ReturnVal to omit?

Thanks for any hint,
Olaf

Hi,

like this:

v_ReturnVal = OMIT_VALUE;


Best regards,
Botond
