Operator overloading question

[39ster]

In one of my classes i have an '=' operator that looks like this:

CBuffer& CBuffer::operator=(const CBuffer& pBuffer);

When i use this in the below code it treats it as a reference, instead of calling the operator"

void someFunc(CBuffer& pBuff)
{
  CBuffer something = pBuff; //treats it as a reference, rather than calling the overloaded operator.
}

I have to do it like this for it to call the operator:

void someFunc(CBuffer& pBuff)
{
  CBuffer something;
  something = pBuff;
}

Is there anyway i can make it work how i got it in the first example?
