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.

       X/Open  defines	no  error  conditions.	In this implementation, if the
       window parameter is null or the	str  parameter	is  null,  a  zero  is
       returned.

       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 winnstr may be macros.

PORTABILITY
       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.
