| Every form has an associated pair of <STRONG>curses</STRONG> windows. The form window |
| displays any title and border associated with the window; the form sub- |
| window displays the items of the form that are currently available for |
| selection. |
| |
| The first four functions get and set those windows. It is not neces- |
| sary to set either window; by default, the driver code uses <STRONG>stdscr</STRONG> for |
| both. |
| |
| In the <STRONG>set_</STRONG> functions, window argument of <STRONG>NULL</STRONG> is treated as though it |
| were <STRONG>stsdcr</STRONG>. A form argument of <STRONG>NULL</STRONG> is treated as a request to change |
| the system default form window or subwindow. |
| |
| The function <STRONG>scale_form</STRONG> returns the minimum size required for the sub- |
| window of <EM>form</EM>. |
| |
| |
| </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> |
| Routines that return pointers return <STRONG>NULL</STRONG> on error. Routines that |
| return an integer return one of the following error codes: |
| |
| <STRONG>E_OK</STRONG> The routine succeeded. |
| |
| <STRONG>E_SYSTEM_ERROR</STRONG> |
| System error occurred (see <STRONG>errno(3)</STRONG>). |
| |
| <STRONG>E_BAD_ARGUMENT</STRONG> |
| Routine detected an incorrect or out-of-range argument. |
| |
| <STRONG>E_POSTED</STRONG> |
| The form has already been posted. |
| |
| <STRONG>E_NOT_CONNECTED</STRONG> |
| No items are connected to the form. |
