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 (exclusive of the trailing NUL).

RETURN VALUE

       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 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.
