DESCRIPTION

       These  procedures  are  similar	to the Xlib procedures XInternAtom and XGetAtomName.  Tk_InternAtom returns the atom identifier associated
       with string given by name;  the atom identifier is only valid for the display associated with tkwin.   Tk_GetAtomName  returns  the  string
       associated  with  atom  on tkwin's display.  The string returned by Tk_GetAtomName is in Tk's storage:  the caller need not free this space
       when finished with the string, and the caller should not modify the contents of the returned string.  If there is no atom atom  on  tkwin's
       display, then Tk_GetAtomName returns the string "?bad atom?".

       Tk  caches  the information returned by Tk_InternAtom and Tk_GetAtomName so that future calls for the same information can be serviced from
       the cache without contacting the server.  Thus Tk_InternAtom and Tk_GetAtomName are generally much faster than their Xlib counterparts, and
       they should be used in place of the Xlib procedures.
