curs_instr(3X)									   curs_instr(3X)

       instr,  innstr,	winstr, winnstr, mvinstr, mvinnstr, mvwinstr, 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 characters.  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 number of characters actually read
       into the string.

       Note that all routines except winnstr may be macros.

       The XSI Curses error conditions EILSEQ and EILOVERFLOW associated with extended-level con-
       formance  are  not  yet	detected (this implementation does not yet support XPG4 multibyte
       characters).  SVr4 does not document whether a  length  limit  includes	or  excludes  the
       trailing NUL.

       The  ncurses  library  extends the XSI description by allowing a negative value for n.  In
       this case, the functions return the string ending at the right margin.
