mouse interface
.Sh SYNOPSIS
.Cd "pseudo-device mouse 1"
.Sh DESCRIPTION
The Atari mouse driver supports both the original Atari mouse and the third
party 3-button mouse that has its middle button connected to the up-switch
of the second joystick port. To accomodate X11 users with a standard mouse,
the driver is able to emulate the middle button. See the section on ioctls
for more info.
.Pp
.Bl -tag -width xx
.It Sy Supported ioctls
.Bl -tag -width MIOCG3B_EMUL -compact
.It MIOCS3B_EMUL
This ioctl turns the middle button emulation on or off depending on its
argument. The middle button event is triggered by simultaneously pressing
the left and right buttons. The default emulation mode is on.
.Pp
Note that the emulation status is retained across multiple open/close calls.
.It MIOCG3B_EMUL
This ioctl allows you to get the actual status of the emulation mode.

.Bl -tag -width xx
.It Sy Interface description
The Atari mouse interface works on a minimal emulation of Sun's Firm_event
structures. The primary reason for this is easy interfacing with X11.
.Pp
The movement and button events are read as structures of the form:
.Bd -literal
typedef struct Firm_event {
u_int_16_t id; /* key or MS_* or LOC_[XY]_DELTA */
u_int_16_t pad; /* unused */
int_16_t value; /* VKEY_{UP,DOWN} or locator delta */
struct timeval time; /* time stamp of the event */
}
.Pp
The values of 'id' concerning the mouse:
.Bd -literal
#define MS_LEFT 0x7f20 /* left mouse button */
#define MS_MIDDLE 0x7f21 /* middle mouse button */
#define MS_RIGHT 0x7f22 /* right mouse button */
#define LOC_X_DELTA 0x7f80 /* mouse delta-X */
#define LOC_Y_DELTA 0x7f81 /* mouse delta-Y */
.Ed
.Pp
The values of 'value' concerning a button event:
.Bd -literal
#define VKEY_UP 0 /* a button went up */
#define VKEY_DOWN 1 /* a button went down */
.Ed
.Sh FILES
.Bl -tag -width /dev/mouse0 -compact
.It Pa /dev/mouse0
real mouse device
.It Pa /dev/mouse
currently active mouse device
.El

.Sh BUGS
The time interval that defines 'simultaneous' cannot be set.
