Answer: In Motif 1.x, use XmStringGetLtoR:

    char *str;
    XmString xmstr;
    XmStringGetLtoR(xmstr, XmSTRING_DEFAULT_CHARSET, &str);


In Motif 2.x, use XmStringUnparse:

    str = XmStringUnparse(xmstr, NULL, 0, XmCHARSET_TEXT, NULL, 0, NULL);


In both cases, you should free the string to avoid a memory leak:

    XtFree(str);
