Defined as static functions in <code>src\vgui2\controls\BitmapImagePanel.cpp</code> and as <code>CopyString</code> in <code>src\dlls\AI_ResponseSystem.cpp</code>, this function simply returns a pointer to a clone of the string parameter.  This function handles the repetative code that is seen when copying a string and makes it an inline function.  If copied to <code>src\game_shared\util_shared.h</code>, this function could come in handy at times.
