.SH DESCRIPTION
.SS Purpose
Use \*f to determine the following information for a \s-2CHOICE\s+2 input
device associated with a given workstation type:
.RS
.sp .3
\(bu   Number and list of available prompt/echo types
.sp .2
\(bu   Default echo volume
.sp .2
\(bu   Default input data record
.sp .2
\(bu   Maximum number of available choices
.RE
.LP
Since the default prompt/echo type for all input devices is 1, the default
input data record is for that prompt/echo type.  There are no default input
data records for prompt/echo types other than 1.
.SS C Input Parameters
.LP
Applications using the \s-2C\s+2 binding must create a buffer to be used by this
function as memory space for storing portions of the device data.
This buffer is passed as the \fIstore\fP argument.
.LP 
The store buffer is a data area managed by \s-2PHIGS\s+2. While the 
application is responsible for creating the initial buffer through a call to 
\s-2CREATE STORE\s+2, \s-2PHIGS\s+2 manages this area such that there is
sufficient memory for the specific inquiry. The choice device data record
within the store buffer is accessed via the pointer returned in \fIchoice_data\fP.
.IP \fItype\fP
The workstation type with which the device is associated.
.IP \fIdevice\fP
The device number of the choice device.
See the \fIAvailable Devices\fP section of \s-2INITIALIZE CHOICE 3\s+2
for a description of the available devices.
.IP \fIstore\fP
The memory buffer \s-2PHIGS\s+2 is to use for storing the information
returned for the Pchoice_data3 structure.  This memory is not used for the data
returned in the Pint_list structure.
This buffer must exist prior to calling this function (see
\s-2CREATE STORE (3P)\s+2).
.SS C Output Parameters
.IP \fIerror_ind\fP
The error indicator.  See the \fIExecution\fP section below for a
description of its use.  See the \fIErrors\fP section below for the
possible values it may return.
.IP \fImax_choices\fP
Maximum number of choices.
.IP \fIpets\fP
A pointer to a list of available prompt/echo types.
Pint_list is defined in phigs.h as follows:
.nf
.ta .5i +1i +1.25i
.sp .4
typedef struct {
.sp .2
	Pint	num_ints;	/* number of Pints in list */
	Pint	*ints;	/* list of integers        */
.sp .2
} Pint_list;
.fi
.IP
The \fInum_ints\fR component specifies the number of elements in the list.
The \fIints\fR component is a pointer to a list \fInum_ints\fR long.
.IP
The application must allocate memory for \fIlen\fR elements in the
list of \fIints\fR.
.IP \fIecho_vol\fP
A pointer to a Plimit3 structure defining the
\fIx\fP, \fIy\fP, and \fIz\fP
components of the echo volume, in Device Coordinates.
Plimit3 is defined in phigs.h as follows:
.sp .4
.ta .5i +1i  +1i
.nf
typedef struct {
.sp .2
	Pfloat	x_min;	/* minimum x coordinate value */
	Pfloat	x_max;	/* maximum x coordinate value */
	Pfloat	y_min;	/* minimum y coordinate value */
	Pfloat	y_max;	/* maximum y coordinate value */
	Pfloat	z_min;	/* minimum z coordinate value */
	Pfloat	z_max;	/* maximum z coordinate value */
.sp .2
} Plimit3;
.fi
.IP \fIchoice_data\fP
A pointer to a Pchoice_data3 pointer.
PHIGS assigns this pointer to the location in the Pstore structure that
contains the device's data record contents.
Pchoice_data3 is defined in phigs.h as follows:
.sp
.ta .5i +.5i +1i +1i
.nf
typedef struct {
.sp .2
      union {
	struct {
		Pint	unused;
	} pet_r1;
	struct {
		Pint	num_prompts;	/* number of alternatives */
		Ppr_switch	*prompts;	/* array of prompts */
	} pet_r2;
	struct {
		Pint	num_strings;	/* number of choice strings */
		char	**strings;	/* array of choice strings */
	} pet_r3;
	struct {
		Pint	num_strings;	/* number of alternatives */
		char	**strings;	/* array of strings */
	} pet_r4;
	struct {
		Pint	struct_id;	/* struct identifier */
		Pint	num_pick_ids;	/* number of alternatives */
		Pint	*pick_ids;	/* array of pick identifiers */
	} pet_r5;
      } pets;
.sp .2
} Pchoice_data3;
.fi
.SS Execution
\*f returns the default data of the specified choice device.  This data is
stored in the workstation description table associated with the workstation
type.
See \s-2INITIALIZE CHOICE 3\s+2 for a description of the prompt/echo types,
echo volume, and data record contents, and how to set these values.
.LP
In the event of an error, the \fIerror indicator\fP 
indicates the error number of the error detected, and no other output data
is returned.  If no error is detected, the \fIerror indicator\fP 
is set to zero, and the inquired information will be available in the output
parameters.  Since this is an inquiry function, \s-2ERROR HANDLING\s+2 is not
invoked when an error is detected by this function.
.SH ERRORS

and use the specific workstation type
.IP 061
Ignoring function, specified workstation is neither of category \s-2INPUT\s+2
nor of category \s-2OUTIN\s+2
.IP 250
