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 Curses defines no error conditions.  In this implementation:

       •   If the win parameter is null, an error is returned,

       •   If the chstr parameter is null, an error 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.
