- * Returns the name of the display XOpenDisplay would use. This is better
- * than just printing the "display" variable in a program because that
- * could be NULL and/or there could be an environment variable set.
- * This makes it easier for programmers to provide meaningful error
- * messages.
- *
- *
- * For example, this is used in XOpenDisplay() as
- * strncpy( displaybuf, XDisplayName( display ), sizeof(displaybuf) );
- * if ( *displaybuf == '\0' ) return( NULL );
- * This check is actually unnecessary because the next thing is an index()
- * call looking for a ':' which will fail and we'll return(NULL).
