instr, innstr, winstr, winnstr, mvinstr, mvinnstr, mvwin-
str, mvwinnstr - get a string of characters from a curses
window
#include <curses.h>
int instr(char *str);
int innstr(char *str, int n);
int winstr(WINDOW *win, char *str);
int winnstr(WINDOW *win, char *str, int n);
int mvinstr(int y, int x, char *str);
int mvinnstr(int y, int x, char *str, int n);
int mvwinstr(WINDOW *win, int y, int x, char *str);
int mvwinnstr(WINDOW *win, int y, int x, char *str, int
n);
These routines return a string of characters in str,
extracted starting at the current cursor position in the
named window. Attributes are stripped from the charac-
ters. The four functions with n as the last argument
return a leading substring at most n characters long
(exclusive of the trailing NUL).
All of the functions return ERR upon failure, or the num-
ber of characters actually read into the string.
X/Open Curses defines no error conditions. In this imple-
mentation:
o If the win parameter is null, an error is returned,
o If the chstr parameter is null, an error is returned,
Functions with a "mv" prefix first perform a cursor move-
ment using wmove, and return an error if the position is
outside the window, or if the window pointer is null.
Note that all routines except winnstr may be macros.
SVr4 does not document whether a length limit includes or
excludes the trailing NUL.
The ncurses library extends the XSI description by allow-
ing a negative value for n. In this case, the functions
return the string ending at the right margin.
