Thread: Something I'm Missing...

I can't figure out why i'm getting this error message. I know it's something simple.

Code:

void getSFPTransceiver(int device_id)
{
  uint16_t temp_trans;
  SFP_A0_T *a0_ptr = ((SFP_A0_T *)&(sfp[device_id].addr.a0[0])); 
  
  for(a0_ptr->transceiver[1] && BIT(4))                      //<-- line 411
    {
      temp_trans = 0x00;
    }

  description[device_id].transceiver_i[1] = transceiver_adr3[temp_trans];

}

For loops have three parts, separated with semicolons. Perhaps you want "if".

Also, if you're trying to do bitwise and, use & instead of &&.

Duh!...

Thanks very much.
