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 (exclu‐
       sive of the trailing NUL).

       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

       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 allowing a  negative
       value  for  n.  In this case, the functions return the string ending at
       the right margin.
