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.

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

   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.


   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.
