strdup is useful for duplicating strings to store them off to pointers. Remember to delete the duplicated string once you're done with it.

-Defined as a static <code>CloneString</code> in <code>src\vgui2\controls\BitmapImagePanel.cpp</code> and as a static <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 repetitive 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. It is also valid to use <code>strdup</code> to achieve the same results.
