.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE PREDEFINED COLOUR REPRESENTATION\s+2 to determine
the predefined colour representation for a specified workstation
type at a given colour index.
.
.SS C Input Parameters
.IP \fItype \fP
Type of workstation.
.IP \fIindex \fP
Entry in the workstation table of predefined colour representations
to be returned.
.
.SS C Output Parameters
.IP \fIerror_ind\fP
A pointer to the location to store the error number of any error
detected by this function.
.IP \fIbundle\fP
A pointer to a Pcolr_rep structure in which the system returns
the colour representation at \fIindex\fP on the workstation table
of predefined colour representations. Pcolr_rep is defined in phigs.h as:
.ta .5i +1i +1i
.nf
.sp .2
typedef union {
.sp .2
Prgb rgb; /* Red Green Blue colour specification */
Pcieluv cieluv; /* CIE L*U*V* colour specification */
Phls hls; /* Hue Lightness Saturation colour specification */
Phsv hsv; /* Hue Saturation Value colour specification */
Pdata unsupp; /* Colour in unsupported colour model */
.sp .2
} Pcolr_rep;
.sp .2
.fi
.IP
Prgb is defined in phigs.h as follows:
.nf
.ta .5i +1i +1i
.sp .2
typedef struct {
.sp .2
Pfloat red; /* red, hue, etc */
Pfloat green; /* green, saturation, lightness, etc */
Pfloat blue; /* blue, value, saturation, etc */
.sp .2
} Prgb;
.fi
.IP
Pcieluv is defined in phigs.h as follows:
.nf
.ta .5i +1i +1i
.sp .2
typedef struct {
.sp .2
Pfloat cieluv_x; /* x coefficient */
Pfloat cieluv_y; /* y coefficient */
Pfloat cieluv_y_lum; /* y luminance */
.sp .2
} Pcieluv;
.fi
.bp
.IP
Phsv is defined in phigs.h as follows:
.nf
.ta .5i +1i +1i
.sp .2
typedef struct {
.sp .2
Pfloat hue; /* hue */
Pfloat satur; /* saturation */
Pfloat value; /* value */
.sp .2
} Phsv;
.fi
.IP
Phls is defined in phigs.h as follows:
.nf
.ta .5i +1i +1i
.sp .2
typedef struct {
.sp .2
Pfloat hue; /* hue */
Pfloat lightness; /* lightness */
Pfloat satur; /* saturation */
.sp .2
} Phls;
.fi
.IP
Pdata is defined in phigs.h as follows:
.nf
.ta .5i +1i +1i
.sp .2
typedef struct {
.sp .2
size_t size; /* size of data */
char *data /*pointer to data */
.sp .2
} Pdata;
.fi
.SS Execution
.LP
If the inquired information is available, the error indicator is returned
as zero and values are returned in the output parameters.
.LP
If the inquired information is not available, the values returned in the
output parameters are undefined and the error indicator is
set to one of the below error numbers to indicate the reason for
nonavailability.
.LP
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, \s-2*\s+2, \s-2*\s+2, \s-2*\s+2)
.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 052
Ignoring function, workstation type not recognized by the implementation
.IP 059
Ignoring function, the specified workstation does not have
output capability (in other words, the workstation category is neither
\s-2OUTPUT\s+2, \s-2OUTIN\s+2, nor \s-2MO\s+2)
.IP 062
Ignoring function, this information is not available for this
\s-2MO\s+2 workstation type
.IP 113
Ignoring function, the colour index value is less than zero
.IP 102
Ignoring function, the specified representation has not been predefined
on this workstation
