.SH DESCRIPTION
.SS Purpose
Use \*f to determine the following information for a \s-2STRING\s+2 input
device associated with a given workstation type:
.RS
.sp .2
\(bu Number and list of available prompt/echo types
.sp .2
\(bu Default echo area
.sp .2
\(bu Default input data record
.sp .2
\(bu Maximum string buffer size
.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 string device data record
within the store buffer is accessed via the pointer returned in \fIstring_data\fP.
.IP \fItype\fP
The workstation type with which the device is associated.
.IP \fIdevice\fP
The device number of the string device.
See the \fIAvailable Devices\fP section of \s-2INITIALIZE STRING\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 Pstring_data 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_buf_size\fP
Maximum input buffer size.
.IP \fIpets\fP
A pointer to the 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_area\fP
A pointer to an object of type Plimit that represents the echo area of
the device. Plimit is defined in phigs.h as follows:
.sp .4
.nf
.ta .5i +1i +1i
.sp .2
typedef struct {
.sp .2
Pfloat x_min; /* x min */
Pfloat x_max; /* x max */
Pfloat y_min; /* y min */
Pfloat y_max; /* y max */
.sp .2
} Plimit;
.IP
.fi
.IP \fIstring_data\fP
A pointer to a Pstring_data pointer.
PHIGS assigns this pointer to the location in the Pstore structure that
contains the device's data record contents.
Pstring_data is defined in phigs.h as follows:
.sp .4
.ta .5i +.5i +.5i +.5i
.nf
typedef struct {
.sp .2
Pint buffer_size; /* input buffer size */
Pint init_pos; /* initial editing position */
union {
.sp .2
struct {
.sp .2
Pint unused;
.sp .2
} pet_r1;
.sp .2
} pets;
.sp .2
} Pstring_data;
.fi
.SS Execution
\*f returns the default data of the specified string device. This data is
stored in the workstation description table associated with the workstation
type.
See \s-2INITIALIZE STRING\s+2 for a description of the prompt/echo types,
echo area, 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
.IP 002
Ignoring function, function requires state (\s-2PHOP, *, *, *\s+2)
.IP 052
Ignoring function, workstation type not recognized by the implementation
.IP 051
Ignoring function, this information is not yet available
for this workstation type; open a workstation of this type
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
Ignoring function, the specified device is not available
on the specified workstation
