NAME
inchstr, inchnstr, winchstr, winchnstr, mvinchstr, mvinchnstr,
mvwinchstr, mvwinchnstr - get a string of characters (and attributes)
from a curses window
SYNOPSIS
#include <ncurses/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 inch(3NCURS-
ES)].
RETURN VALUE
All routines return the integer ERR upon failure and an integer value
other than ERR upon successful completion (the number of characters re-
trieved, 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.
Functions with a "mv" prefix first perform a cursor movement using
wmove, and return an error if the position is outside the window, or if
the window pointer is null.
NOTES
Note that all routines except winchnstr may be macros. SVr4 does not
document whether the result string is zero-terminated; it does not doc-
ument 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.
