NAME


vuidmice, vuidm3p, vuidm4p, vuidm5p, vuid2ps2, vuid3ps2 - converts mouse
protocol to Firm Events

SYNOPSIS


#include <sys/stream.h>


#include <sys/vuid_event.h>


#include <sys/vuid_wheel.h>


int ioctl(fd, I_PUSH, vuidm3p);


int ioctl(fd, I_PUSH, vuidm4p);


int ioctl(fd, I_PUSH, vuidm5p);


int ioctl(fd, I_PUSH, vuid2ps2);


int ioctl(fd, I_PUSH, vuid3ps2);


DESCRIPTION


The STREAMS modules vuidm3p, vuidm4p, vuidm5p, vuid2ps2, and vuid3ps2
convert mouse protocols to Firm events. The Firm event structure is
described in <sys/vuid_event.h>. Pushing a STREAMS module does not
automatically enable mouse protocol conversion to Firm events. The
STREAMS module state is initially set to raw or VUID_NATIVE mode which
performs no message processing. You must change the state to
VUID_FIRM_EVENT mode to initiate mouse protocol conversion to Firm
events. This can be accomplished by the following code:

int format;
format = VUID_FIRM_EVENT;
ioctl(fd, VUIDSFORMAT, &format);


You can also query the state of the STREAMS module by using the
VUIDGFORMAT option.

int format;
int fd; /* file descriptor */
ioctl(fd, VUIDGFORMAT, &format);
if ( format == VUID_NATIVE );
/* The state of the module is in raw mode.
* Message processing is not enabled.
*/
if ( format == VUID_FIRM_EVENT );
/* Message processing is enabled.
* Mouse protocol conversion to Firm events
* are performed.


The remainder of this section describes the processing of STREAMS
messages on the read- and write-side.

Read Side Behavior


M_DATA
Incoming messages are queued and converted to Firm events.


M_FLUSH
The read queue of the module is flushed of all its data
messages and all data in the record being accumulated are
also flushed. The message is passed upstream.


Write Side Behavior


M_IOCTL
Messages sent downstream as a result of an ioctl(2)
system call. The two valid ioctl options processed by
the vuidmice modules are VUIDGFORMAT and VUIDSFORMAT.


M_FLUSH
The write queue of the module is flushed of all its data
messages and the message is passed downstream.


VUIDGFORMAT
This option returns the current state of the STREAMS
module. The state of the vuidmice STREAMS module may
either be VUID_NATIVE (no message processing) or
VUID_FIRM_EVENT (convert to Firm events).


VUIDSFORMAT
This option sets the state of the STREAMS module to
VUID_FIRM_EVENT. If the state of the STREAMS module is
already in VUID_FIRM_EVENT, this option is non-
operational. It is not possible to set the state back to
VUID_NATIVE once the state becomes VUID_FIRM_EVENT. To
disable message processing, pop the STREAMS module out by
calling ioctl(fd, 1I_POP, vuid*).


The following wheel support ioctls are defined for PS/2 mouse only:

VUIDGWHEELCOUNT
This ioctl takes a pointer to an integer as argument
and sets the value of the integer to the number of
wheels available on this device.


VUIDGWHEELINFO
This command returns static information about the
wheel that does not change while a device is in use.
Currently the only information defined is the wheel
orientation which is
either VUID_WHEEL_FORMAT_VERTICAL or
VUID_WHEEL_FORMAT_HORIZONTAL.

typedef struct {
int vers;
int id;
int format;
} wheel_info;

The ioctl takes a pointer to "wheel_info" structure
with the "vers" set to the current version of the
"wheel_info" structure and "id" set to the id of the
wheel for which the information is desired.


VUIDSWHEELSTATE
VUIDGWHEELSTATE
VUIDSWHEELSTATE sets the state of the wheel to that
specified in the stateflags. VUIDGWHEELSTATE returns
the current state settings in the stateflags field.

stateflags is an OR'ed set of flag bits. The only
flag currently defined is VUID_WHEEL_STATE_ENABLED.

When stateflags is set to VUID_WHEEL_STATE_ENABLED the
module converts motion of the specified wheel into
VUID events and sends those up stream.

Wheel events are disabled by default.

Applications that want to change a flag should
first get the current flags and then change only the
bit they want.

typedef struct {
int vers;
int id;
uint32_t stateflags;
} wheel_state;

These ioctls take pointer to 'wheel_state' as an
argument with the 'vers' and 'id' members filled up.
These members have the same meaning as that for
'VUIDGWHEELINFO' ioctl.
