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.

SEE ALSO

       ncurses(3NCURSES).
