form_opts - set and get form options |
#include <form.h> |
The function set_form_opts sets all the given form’s option bits (form option bits may be logically-OR’ed together). The function form_opts_on turns on the given option bits, and leaves others alone. The function form_opts_off turns off the given option bits, and leaves others alone. The function form_opts returns the form’s current option bits. The following options are defined (all are on by default): |
O_NL_OVERLOAD |
Overload the REQ_NEW_LINE forms driver request so that calling it at the end of a field goes to the next field. |
O_BS_OVERLOAD |
Overload the REQ_DEL_PREV forms driver request so that calling it at the beginning of a field goes to the previous field. |
Except for form_opts, each routine returns one of the following: |
E_OK |
The routine succeeded. |
E_SYSTEM_ERROR |
System error occurred (see errno). |
curses(3X), form(3X). |
The header file <form.h> automatically includes the header file <curses.h>. |
These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions. |
