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 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.
