title: Inline function naming convention
body: <p>I was wondering if there is a sort of naming convention when using inline functions.</p>
  
  <p>Say I am implementing an API and want to let the user decide if he wants to use a normal function or an inline function(both doing the same thing), is there a naming convention how to make it visible to the outside world that a function is potentially inline ?
  I know that I could look into the .h or .inl file  </p>
  
  <p><strong>EDIT:</strong>
  I feel the need to clarify some points since it seems that I wasn't clear enough in the first place.</p>
  
  <p>Lets say I have a function which accepts three values.
  Something like:</p>
  
  <pre><code>bool MyClass::AddTwoNumbersAndCheckIfBigger(int summandOne, int summandTwo, int biggerNr)
  {
      bool isBigger = false;
      int sum = summandOne+summandTwo;
      if(sum &gt; biggerNr)
      {
          isBigger = true;
      }
      return isBigger;
  }
  </code></pre>
  
  <p>This function could be called a single time up to  x > 1000000.
  If I call it once I would prefer it to just be called normally but if it is called 1000000 times in a for loop I maybe prefer an inline option.</p>
  
  <p>I want to give the developer the possibility to choose between those two options. I am aware of the fact that the compiler is responsible for deciding if its going to be used as an inline function or not but I guess it would be nice if the developer could decide for himself.</p>
  
  <p>The question for the naming convention arises from the fact that I have users\developers who don't look at the header files but only use intellisense for guidance.</p>
