NAME
       instr,  innstr, winstr, winnstr, mvinstr, mvinnstr, mvwinstr, 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 characters.  The four functions with n  as  the  last
       argument  return  a leading substring at most n characters long (exclu-
       sive of the trailing NUL).

RETURN VALUE
       All of the functions return ERR upon failure, or the number of  charac-
       ters 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 multibyte characters).  SVr4 does not docu-
       ment 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.
