NAME
instr, innstr, winstr, winnstr, mvinstr, mvinnstr, mvwin-
str, mvwinnstr - get a string of characters from a curses
window
SYNOPSIS
#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);
DESCRIPTION
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).
RETURN VALUE
All of the functions return ERR upon failure, or the num-
ber of characters actually read into the string.
NOTES
Note that all routines except winnstr may be macros.
PORTABILITY
The XSI Curses error conditions EILSEQ and EILOVERFLOW
associated with extended-level conformance are not yet
detected (this implementation does not yet support XPG4
multi-byte characters). 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.
