NAME
inchstr, inchnstr, winchstr, winchnstr, mvinchstr, mvinchnstr, mvwinchstr, mvwinchnstr - get a string
of characters (and attributes) from a curses window
SYNOPSIS
#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);
DESCRIPTION
These routines return a NULL-terminated array of chtype quantities, 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) operator to extract
the character or the attribute alone from any position in the chstr [see curs_inch(3X)].
RETURN VALUE
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).
No error conditions are defined. If the chstr parameter is null, no data is returned, and the return
value is zero.
NOTES
Note that all routines except winchnstr may be macros. SVr4 does not document whether the result
string is 0-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.
PORTABILITY
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.
