XmGetAtomName — A function that returns the string representation for an atom "XmGetAtomName" "atoms"

XmGetAtomName  returns  the  string  representation for an atom.  It mirrors the Xlib interfaces for atom
       management but provides client-side caching. When and where caching is provided  in  Xlib,  the  routines
       will become pseudonyms for the Xlib routines.

       display   Specifies the connection to the X server

       atom      Specifies the atom for the property name you want returned
