View source for GreGetDefaultAttributes

GreGetDefaultAttributes returns the default values of the attributes indicated in flAttrsMask.

This function is supported by the graphics engine.

==Syntax==
 GreGetDefaultAttributes(hdc, lPrimType, flAttrsMask, pAttrs, pInstance, lFunction)

==Parameters==
;hdc (HDC) - input:Device context handle.
;lPrimType (LONG) - input:Bundle primitive type.
:Indicates the bundle type. Valid primitive values are:
::PRIM_LINE: Line attribute bundle
::PRIM_CHAR: Character attribute bundle
::PRIM_MARKER: Marker attribute bundle
::PRIM_AREA :Pattern attribute bundle
::PRIM_IMAGE: Image attribute bundle
;flAttrsMask (ULONG) - input:Attribute mask.
:Specifies the attributes to be returned corresponding to each attribute in the bundle record. For each set bit, the engine returns the corresponding attribute values and default mask bits.
;pAttrs (PBUNDLE) - input:Pointer to the fixed format bundle record containing the attributes returned.
;pInstance (PVOID) - input:Pointer to instance data.
;lFunction (ULONG) - input:High-order WORD=flags; low-order WORD=NGreGetDefaultAttributes.

==Return Code==
;rc (BOOL) - returns:This function returns the default attribute bit mask. Only bits with corresponding set bits in flAttrsMask are updated. Otherwise, this function returns the error, ATTRS_ERROR.

:Possible Errors Detected: When an error is detected, the graphics engine calls WinSetErrorInfo to post the condition. Reasons for failure of this function include:
:*PMERR_HDC_BUSY
:*PMERR_INV_HDC
:Refer to the "Error Explanations" section of the Presentation Manager Programming Reference for further explanation.

==Sample Code==
<PRE>
#define INCL_GRE_DEVSUPPORT
#include <os2.h>

HDC        hdc;          /*  Device context handle. */
LONG       lPrimType;    /*  Bundle primitive type. */
ULONG      flAttrsMask;  /*  Attribute mask. */
PBUNDLE    pAttrs;
PVOID      pInstance;    /*  Pointer to instance data. */
ULONG      lFunction;
BOOL       rc;

rc = GreGetDefaultAttributes(hdc, lPrimType,
       flAttrsMask, pAttrs, pInstance, lFunction);
