scare_mouse_area(3alleg4)					  Allegro manual					 scare_mouse_area(3alleg4)

NAME

       scare_mouse_area - Helper for hiding the mouse cursor before drawing in an area. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void scare_mouse_area(int x, int y, int w, int h);

DESCRIPTION

       Like  scare_mouse(),  but  will only hide the cursor if it is inside the specified rectangle. Otherwise the cursor will simply be frozen in
       place until you call unscare_mouse(), so it cannot interfere with your drawing.

NAME

       show_os_cursor - Low level function to display the operating system cursor. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int show_os_cursor(int cursor);

DESCRIPTION

       In  case you do not need Allegro's mouse cursor API, which automatically emulates a cursor in software if no other cursor is available, you
       can use this low level function to try to display or hide the system cursor directly.  The  cursor  parameter  takes  the  same	values	as
       select_mouse_cursor.  This function is very similar to calling enable_hardware_cursor, select_mouse_cursor and show_mouse, but will not try
       to do anything if no system cursor is available.

       The most common use for this function is to just call it once at the beginning of the program to tell  it  to  display  the  system  cursor
       inside  the Allegro window. The return value can be used to see if this succeeded or not. On some systems (e.g. DirectX fullscreen) this is
       not supported and the function will always fail, and in other cases only some of the cursors will  work,  or  in  the  case  of	MOUSE_CUR-
       SOR_ALLEGRO, only certain bitmap sizes may be supported.

       You  never  should  use	show_os_cursor	together  with	the  function  show_mouse  and	other functions affecting it (select_mouse_cursor,
       enable_hardware_cursor, disable_hardware_cursor, scare_mouse, unscare_mouse). They implement the standard high level mouse API,	and  don't
       work together with this low level function.

RETURN VALUE

       Returns 0 if a system cursor is being displayed after the function returns, or -1 otherwise.
