curs_instr 3x

NAME

       instr,  innstr, winstr, winnstr, mvinstr, mvinnstr, mvwin-
       str, 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  charac-
       ters.   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 num-
       ber of characters actually read into the string.

NOTES

       Note that all routines except winnstr may be macros.

PORTABILITY

       The XSI Curses error  conditions  EILSEQ  and  EILOVERFLOW
       associated  with  extended-level  conformance  are not yet
       detected (this implementation does not  yet  support  XPG4
       multibyte  characters).   SVr4 does not document whether a
       length limit includes or excludes the trailing NUL.

       The ncurses library extends the XSI description by  allow-
       ing  a  negative value for n.  In this case, the functions
       return the string ending at the right margin.
