winsnstr(3ncurses)


NAME

   insstr,  insnstr,  winsstr,  winsnstr,  mvinsstr, mvinsnstr, mvwinsstr,
   mvwinsnstr - insert string before cursor in a curses window

SYNOPSIS

   #include <curses.h>
   int insstr(const char *str);
   int insnstr(const char *str, int n);
   int winsstr(WINDOW *win, const char *str);
   int winsnstr(WINDOW *win, const char *str, int n);
   int mvinsstr(int y, int x, const char *str);
   int mvinsnstr(int y, int x, const char *str, int n);
   int mvwinsstr(WINDOW *win, int y, int x, const char *str);
   int mvwinsnstr(WINDOW *win, int y, int x, const char *str, int n);

DESCRIPTION

   These routines insert a character string (as many  characters  as  will
   fit on the line) before the character under the cursor.  All characters
   to the right of the cursor are shifted right with  the  possibility  of
   the  rightmost  characters on the line being lost.  The cursor position
   does not change (after moving to y, x, if  specified).   The  functions
   with  n  as  the  last argument insert a leading substring of at most n
   characters.  If n<=0, then the entire string is inserted.

   Special characters are handled as in addch.

RETURN VALUE

   All routines that return an integer return  ERR  upon  failure  and  OK
   (SVr4 specifies only "an integer value other than ERR") upon successful
   completion,  unless  otherwise   noted   in   the   preceding   routine
   descriptions.

   X/Open  defines  no  error  conditions.  In this implementation, if the
   window parameter is null or the str 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 but winsnstr may be macros.

PORTABILITY

   These  functions  are  described  in  the XSI Curses standard, Issue 4,
   which adds const qualifiers to the arguments.

   The Single Unix  Specification,  Version  2  states  that  insnstr  and
   winsnstr  perform  wrapping.  This is probably an error, since it makes
   this group of  functions  inconsistent.   Also,  no  implementation  of
   curses documents this inconsistency.
