curs_inchstr(3X) curs_inchstr(3X)
inchstr, inchnstr, winchstr, winchnstr, mvinchstr, mvinchnstr,
mvwinchstr, mvwinchnstr - get a string of characters (and
attributes) from a curses window
#include <curses.h>
int inchstr(chtype *chstr);
int inchnstr(chtype *chstr, int n);
int winchstr(WINDOW *win, chtype *chstr);
int winchnstr(WINDOW *win, chtype *chstr, int n);
int mvinchstr(int y, int x, chtype *chstr);
int mvinchnstr(int y, int x, chtype *chstr, int n);
int mvwinchstr(WINDOW *win, int y, int x, chtype *chstr);
int mvwinchnstr(WINDOW *win, int y, int x, chtype *chstr, int n);
These routines return a NULL-terminated array of chtype quanti‐
ties, 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 a leading substring at most n
characters long (exclusive of the trailing (chtype)0). Constants
defined in <curses.h> can be used with the & (logical AND) opera‐
tor to extract the character or the attribute alone from any po‐
sition in the chstr [see curs_inch(3X)].
All routines return the integer ERR upon failure and an integer
value other than ERR upon successful completion (the number of
characters retrieved, exclusive of the trailing 0).
X/Open Curses defines no error conditions. In this implementa‐
tion:
• If the win parameter is null, an error is returned,
• If the chstr parameter is null, an error is returned,
Functions with a “mv” prefix first perform a cursor movement us‐
ing wmove, and return an error if the position is outside the
window, or if the window pointer is null.
Note that all routines except winchnstr may be macros. SVr4 does
not document whether the result string is zero-terminated; it
does not document whether a length limit argument includes any
trailing 0; and it does not document the meaning of the return
value.
These functions are described in the XSI Curses standard, Issue
4. It is no more specific than the SVr4 documentation on the
trailing 0. It does specify that the successful return of the
functions is OK.

Comparable functions in the wide-character (ncursesw) library are
described in curs_in_wchstr(3X).
