SYNOPSIS

#include <ncurses/curses.h>

bool is_cleared(const WINDOW *win);
bool is_idcok(const WINDOW *win);
bool is_idlok(const WINDOW *win);
bool is_immedok(const WINDOW *win);
bool is_keypad(const WINDOW *win);
bool is_leaveok(const WINDOW *win);
bool is_nodelay(const WINDOW *win);
bool is_notimeout(const WINDOW *win);
bool is_pad(const WINDOW *win);
bool is_scrollok(const WINDOW *win);
bool is_subwin(const WINDOW *win);
bool is_syncok(const WINDOW *win);
WINDOW * wgetparent(const WINDOW *win);
int wgetdelay(const WINDOW *win);
int wgetscrreg(const WINDOW *win, int *top, int *bottom);

DESCRIPTION

This implementation provides functions which return properties set in the WINDOW structure, allowing it to be “opaque” if the symbol NCURSES_OPAQUE is defined:
is_cleared

returns the value set in clearok

is_idcok

returns the value set in idcok

is_idlok

returns the value set in idlok

is_immedok

returns the value set in immedok

is_keypad

returns the value set in keypad

is_leaveok

returns the value set in leaveok

is_nodelay

returns the value set in nodelay

is_notimeout

returns the value set in notimeout

is_pad

returns TRUE if the window is a pad i.e., created by newpad

is_scrollok

returns the value set in scrollok

is_subwin

returns TRUE if the window is a subwindow, i.e., created by subwin or derwin

is_syncok

returns the value set in syncok

wgetdelay

returns the delay timeout as set in wtimeout.

wgetparent

returns the parent WINDOW pointer for subwindows, or NULL for windows having no parent.

wgetscrreg

returns the top and bottom rows for the scrolling margin as set in wsetscrreg.

RETURN VALUE

These functions all return TRUE or FALSE, except as noted.

NOTES

Both a macro and a function are provided for each name.

PORTABILITY

These routines are specific to ncurses. They were not supported on Version 7, BSD or System V implementations. It is recommended that any code depending on ncurses extensions be conditioned using NCURSES_VERSION.

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.

Free Books

The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.

Education

Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
