curs_instr (3X)                                                                                curs_instr (3X)



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  posi-tion position
       tion 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.

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.
