For modern C programming, defining functions is a two step process. First, you declare a function and its signature using a prototype. Then you define the function by providing a function body that defines what the function does.

curs_inwchstr, inwchstr, inwchnstr, winwchstr, winwchnstr, mvinwchstr, mvinwchnstr, mvwinwchstr, mvwinwchnstr - get a string of wchar_t characters (and attributes) from a curses window SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library .. ] #include <curses.h> int inwchstr(chtype *wchstr); int inwchnstr(chtype *wchstr, int n); int winwchstr(WINDOW *win, chtype *wchstr); int winwchnstr(WINDOW *win, chtype *wchstr, int n); int mvinwchstr(int y, int x, chtype *wchstr); int mvinwchnstr(int y, int x, chtype *wchstr, int n); int mvwinwchstr(WINDOW *win, int y, int x, chtype *wchstr); int mvwinwchnstr(WINDOW *win, int y, int x, chtype *wchstr, int n); DESCRIPTION
These routines return a string of type chtype, holding wchar_t characters, starting at the current cursor position in the named window and ending at the right margin of the window. The four functions with n as the last argument, return the string at most n wchar_t charac- ters long. Constants defined in <curses.h> can be used with the logical AND (&) operator to extract the wchar_t character or the attribute alone from any position in the wchstr (see curs_inwch(3CURSES)). RETURN VALUE
All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion. ATTRIBUTES
See attributes(5) for a description of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |MT-Level |Unsafe | +-----------------------------+-----------------------------+ SEE ALSO

The header file <curses.h> automatically includes the header files <stdio.h>, <unctrl.h> and <widec.h>. Note that all routines except winwchnstr() may be macros. None of these routines can use the color attribute in chtype. SunOS 5.11 31 Dec 1996 curs_inwchstr(3CURSES)
