1147 | some buffer-local variables are built-in, with their values stored | |
1148 | in the buffer structure itself. They are handled differently, | |
1149 | using struct Lisp_Buffer_Objfwd.) | |
1150 | ||
1151 | The `realvalue' slot holds the variable's current value, or a | |
1152 | forwarding pointer to where that value is kept. This value is the | |
1153 | one that corresponds to the loaded binding. To read or set the | |
1154 | variable, you must first make sure the right binding is loaded; | |
1155 | then you can access the value in (or through) `realvalue'. | |

1157 | `buffer' and `frame' are the buffer and frame for which the loaded |
1158 | binding was found. If those have changed, to make sure the right | |
1159 | binding is loaded it is necessary to find which binding goes with | |
1160 | the current buffer and selected frame, then load it. To load it, | |
1161 | first unload the previous binding, then copy the value of the new | |
1162 | binding into `realvalue' (or through it). Also update | |
1163 | LOADED-BINDING to point to the newly loaded binding. | |
