* So to create a text buffer window which takes the top 40% of the original
* window's space, you would execute
- * |[ newwin = #glk_window_open(win, #winmethod_Above | #winmethod_Proportional, 40, #wintype_TextBuffer, 0); ]|
+ * |[ newwin = glk_window_open(win, winmethod_Above | winmethod_Proportional, 40, wintype_TextBuffer, 0); ]|
*
* To create a text grid which is always five lines high, at the bottom of the
* original window, you would do
- * |[ newwin = #glk_window_open(win, #winmethod_Below | #winmethod_Fixed, 5, #wintype_TextGrid, 0); ]|
+ * |[ newwin = glk_window_open(win, winmethod_Below | winmethod_Fixed, 5, wintype_TextGrid, 0); ]|
*
* Note that the meaning of the @size argument depends on the @method argument.
* If the method is %winmethod_Fixed, it also depends on the @wintype argument.

* Consider the example above, where D has collapsed to zero height. Say D was a
* text buffer window. You could make a more useful layout by doing
* |[
- * #winid_t o2;
- * o2 = #glk_window_get_parent(d);
- * glk_window_set_arrangement(o2, #winmethod_Above | #winmethod_Fixed, 3, d);
+ * winid_t o2;
+ * o2 = glk_window_get_parent(d);
+ * glk_window_set_arrangement(o2, winmethod_Above | winmethod_Fixed, 3, d);
* ]|
* That would set D (the upper child of O2) to be O2's key window, and give it a
* fixed size of 3 rows.
*
* If you later wanted to expand D, you could do
- * |[ glk_window_set_arrangement(o2, #winmethod_Above | #winmethod_Fixed, 5, NULL); ]|
+ * |[ glk_window_set_arrangement(o2, winmethod_Above | winmethod_Fixed, 5, NULL); ]|
* That expands D to five rows. Note that, since O2's key window is already set
* to D, it is not necessary to provide the @keywin argument; you can pass %NULL
* to mean <quote>leave the key window unchanged.</quote>
* example, you could change O2's key window to be A, but not B. The key window
* also cannot be a pair window itself.
*
- * |[ glk_window_set_arrangement(o2, #winmethod_Below | #winmethod_Fixed, 3, NULL); ]|
+ * |[ glk_window_set_arrangement(o2, winmethod_Below | winmethod_Fixed, 3, NULL); ]|
* This changes the constraint to be on the <emphasis>lower</emphasis> child of
* O2, which is A. The key window is still D; so A would then be three rows high
* as measured in D's font, and D would get the rest of O2's space. That may not
* be what you want. To set A to be three rows high as measured in A's font, you
* would do
- * |[ glk_window_set_arrangement(o2, #winmethod_Below | #winmethod_Fixed, 3, a); ]|
+ * |[ glk_window_set_arrangement(o2, winmethod_Below | winmethod_Fixed, 3, a); ]|
*
* Or you could change O2 to a proportional split:
- * |[ glk_window_set_arrangement(o2, #winmethod_Below | #winmethod_Proportional, 30, NULL); ]|
+ * |[ glk_window_set_arrangement(o2, winmethod_Below | winmethod_Proportional, 30, NULL); ]|
* or
- * |[ glk_window_set_arrangement(o2, #winmethod_Above | #winmethod_Proportional, 70, NULL); ]|
+ * |[ glk_window_set_arrangement(o2, winmethod_Above | winmethod_Proportional, 70, NULL); ]|
* These do exactly the same thing, since 30% above is the same as
* 70% below. You don't need to specify a key window with a proportional
* split, so the @keywin argument is %NULL. (You could actually specify either A
