BOOL GpiQueryDefAttrs(hps, lPrimType, flAttrMask, pbunAttrs)
HPS hps;              /* presentation-space handle                   */
LONG lPrimType;       /* primitive type                              */

The GpiQueryDefAttrs function retrieves the default attributes for a
primitive. The default attributes define the values given to a presentation
space's attributes when that presentation space is reset. The default
attributes also define the value of attributes when they are explicitly set
to the default by using the GpiSetAttrs function.
 
Parameter   Description
────────────────────────────────────────────────────────────────────────────
 
hps         Identifies the presentation space.
 
lPrimType   Specifies which primitive type to retrieve attributes for. It
            can be one of the following values:
 
            Value        Meaning
            ────────────────────────────────────────────────────────────────
            PRIM_AREA    Area primitives
 
            PRIM_CHAR    Character primitives
 
            PRIM_IMAGE   Image primitives
 
            PRIM_LINE    Line and arc primitives
 
            PRIM_MARKER  Marker primitives
 
flAttrMask  Specifies which attributes to retrieve. The values for this
            parameter depend on the primitive type specified by the
            lPrimType parameter. This parameter can be any combination of
            the following values for a specific type:
 
            Type         Values
            ────────────────────────────────────────────────────────────────
            PRIM_AREA    ABB_COLOR, ABB_BACK_COLOR, ABB_MIX_MODE,
                         ABB_BACK_MIX_MODE, ABB_SET, ABB_SYMBOL,
                         ABB_REF_POINT
 
            PRIM_CHAR    CBB_COLOR, CBB_BACK_COLOR, CBB_MIX_MODE,
                         CBB_BACK_MIX_MODE, CBB_SET, CBB_MODE, CBB_BOX,
                         CBB_ANGLE, CBB_SHEAR, CBB_DIRECTION
 
            PRIM_IMAGE   IBB_COLOR, IBB_BACK_COLOR, IBB_MIX_MODE,
                         IBB_BACK_MIX_MODE
 
            PRIM_LINE    LBB_COLOR, LBB_MIX_MODE, LBB_WIDTH, LBB_GEOM_WIDTH,
                         LBB_TYPE, LBB_END, LBB_JOIN
 
            PRIM_MARKER  MBB_COLOR, MBB_BACK_COLOR, MBB_MIX_MODE,
                         MBB_BACK_MIX_MODE, MBB_SET, MBB_SYMBOL, MBB_BOX
 
            If this parameter is zero, the function does not retrieve
            attributes but still returns a mask that specifies the
            attributes using default values.
 
pbunAttrs   Points to the structure that receives the default attribute
            values for each attribute specified by the flAttrMask parameter.
            The type of structure depends on the value of the lPrimType
            parameter; it can be one of following structures:
 
            Type         Structure
            ────────────────────────────────────────────────────────────────

            PRIM_LINE    LINEBUNDLE
 
            PRIM_MARKER  MARKERBUNDLE
 
Return Value
 
The return value is GPI_OK if the function is successful or GPI_ERROR if an
error occurs.
 
Errors
 
Use the WinGetLastError function to retrieve the error value, which may be
one of the following:
 
    PMERR_HUGE_FONTS_NOT_SUPPORTED
